When multiple buffers are open, the edit window says "Close" for ^X
instead of "Exit" (when one buffer is open). In the help viewer ^X
says "Close". Apparently the idea is that ^X should say "Exit" only
when pressing ^X leads to exiting from nano. Pressing ^X in the file
browser does not exit from nano, so make it say "Close" instead.
(The help viewer says "Close" since version 2.8.6, commit 934a2192.)
When using --preserve, ^S and ^Q are "eaten" by the terminal and
do not reach nano: they have no effect in nano, so the help lines
and the help texts should not mention these shortcuts.
Also, to keep the help lines in the help viewer neatly arranged,
^L is not bound there when --preserve is used.
Further down, the <Backspace> key is bound to do_page_up() for MHELP
and MBROWSER, so this earlier binding should exclude MBROWSER.

Bug existed since version 2.9.2, commit 8581e702.
Set the Meta flag only for the regular Meta keystrokes: "M-" plus a
printable ASCII character. The special keycodes are unique and do
not need any extra flags to differentiate them.
This function allows the user to "make space": annihilating lines or
regions while keeping intact for pasting the stuff in the cutbuffer
that was cut or copied earlier.

The bindings for F1 to F12 are there for compatibility with Pico.
But Pico does not know anything about F13 to F16; for unknown reasons
they were added to nano. They seem hardly useful: normal keyboards
do not have the F13 to F16 keys, and very few people know that they
can "produce" those keys by holding Shift with F1 to F4. But typing
Shift plus F1 to F4 are just as "hard" as, for example, M-G and M-W,
so why anyone would want to use the first ones...? Especially since
many other functions of nano can only be accessed through Meta and
Control combinations.
Furthermore, F13 to F15 haven't been shown in the help texts since
version 2.3.3, so for more than four years no new user will have
learned about those keystrokes.
The rare user who wants these strange bindings can easily make them
herself.
The 'wrap_at' variable, removed in commit e90b7cf4, is actually needed
to store the original value of the --fill option when it is negative.
Otherwise, changing the screen width will not update the wrapping point
properly.

The ^P and ^N keystrokes for Older and Newer are relevant to searching
and should be visible in the help lines. FullJustify, paragraph jumps,
and top/tail jumping are there only for compatibility with Pico but
don't make any sense there, so it's no problem if they are pushed out
of view.
Rename not only the bindable functions, but more importantly reword the
tags that are shown for ^P and ^N in the help lines: "Older" / "Newer",
because these are clearer and not awkward abbreviations.
When something is spotlighted, it should survive a refresh of
the screen and an excursion to a help text, so the spotlight
should get painted whenever the edit window is drawn.

The binding was made only to have *something* bound by default to the
'cutwordleft' function. But now that <Ctrl+Shift+Delete> is available
*and* visible in the help text, the M-| binding is superfluous.
So that the user can do 'bind ^H cutwordleft all' in their nanorc
to make ^H (and sometimes also <Ctrl+Backspace>) delete the word
to the left of the cursor while <Backspace> continues to delete
just one character.
On FreeBSD and NetBSD (when reached through ssh from a Linux machine)
this has the absurd effect of making <Ctrl+Backspace> do a 'cutwordleft'
by default, out of the box, without needing any rebindings. Weird, but
wonderful, because the ideal behavior.
Also ensure that <Shift+Delete> always does a Backspace.
This makes that we have the following set of "congruent" keys:
<Tab> moves text to the right,
<Shift+Tab> moves text to the left,
<Delete> "eats" a character to the right,
<Shift+Delete> "eats" a character to the left,
<Ctrl+Delete> "eats" a word to the right,
<Shift+Ctrl+Delete> "eats" a word to the left.
These are available in the menus where they are relevant: the Write-Out
and the Insert menu, respectively. Having them duplicated in the main
menu is inconsistent and eats precious keystrokes. (Sorry, Chris.)
Since the last version, the user can filter an entire buffer through
an external command. This external command can also be a formatting
program, so there is no longer any need for this specific and special
formatter command.
There are at least three other ways to achieve the thing that it did:
^End, M-/, and ^W^V. No need to have a fourth way by default.
For symmetry, also unassign the corresponding binding for M-|.
The 'cutwordright' function has gotten ^Delete as its default binding,
so the 'cutwordleft' function needs a default binding too -- also to
keep the items on the two help lines nicely paired. M-| was chosen
because it is close to the Backspace key on many keyboard layouts.
As the help viewer is almost a normal buffer, commands that make sense
-- like searching backwards, and searching the previous occurrence --
should work in the help viewer too.
In addition, show all Search commands prominently in the help lines of
the help viewer, so that users are likely to notice them and will maybe
infer that they work in the editor itself too.
This fixes https://savannah.gnu.org/bugs/?54368.

Put "Where Was" in its place, to make the symmetry of ^W/M-W/^Q/M-Q
somewhat clearer. Also, conditionally reshuffle "Save File", to try
and keep menu items nicely paired.
Bind the until-now unbound function 'cutwordright' to <Ctrl+Delete>.
The complementary function, 'cutwordleft', is not bound by default
because on many terminals the keystroke <Ctrl+Backspace> generates
^H -- the canonical ASCII backspace character. We cannot change the
existing action of ^H without upsetting some users.

In theory it would be possible to allow rebinding also F17...F63,
but nano does not recognize escape sequences for these high-order

when pressing function keys, I am guessing that no one has these
high-order keys, or at least that no one uses them.

This makes things symmetrical: ^W starts a forward search, ^Q starts

When just scrolling and the cursor does not need to change position
(that is: it is not on the first or last row of the edit window),
then edit_scroll() has handled everything and there is no need to
additionally redraw anything or update 'placewewant'.
The slash is easier to read than the underscore (which almost
disappears at the bottom of the screen), and easier to type
(no Shift needed on a US keyboard), and it kind of harmonizes
with the ^\ for Replace and the M-/ for End-of-buffer.
In this way a single keystroke can produce a fragment of text or a
series of commands, or a mix of the two. It is like a prerecorded
macro.

When not finding a .nanorc file in the user's home directory, nano will
look for a nanorc file in $XDG_CONFIG_HOME and in the ~/.config/nano/

home directory, nano will look for (or create) the history files in
$XDG_DATA_HOME or in the ~/.local/share/nano/ fallback directory.

File formats, appending and prepending, and backups are not available
when --enable-tiny is used, so prevent all relevant pieces of code from
getting compiled. And correct two misspelled ENABLE_TINY to NANO_TINY.
This also groups ^I and ^M together, and cutwordleft and cutwordright
(when they are bound). It furthermore makes that less pairs are now
mixed and instead consist of either two Ctrl or two Meta combos. In
short: it looks better in the default config. The only sacrifice is
that Verbatim is now split off from the other "inserting" keys.
The interval 2013-2017 for the Free Software Foundation is valid
because in those years there were releases with changes by either
Chris or David, and the GNU maintainers guide advises to mention
a new year in all files of a package, not just in the ones that
actually changed, and be done with it for the rest of the year.
On some terminal emulators, Ctrl+Home and Ctrl+End produce special
keycodes, distinct from plain Home and End. Make the users of those
emulators (and of the Linux console) glad by making ^Home and ^End
do the obvious thing, and the combinations with Shift too.
When UTF-8 is available, use actual arrows instead of untranslated words
to indicate the cursor keys. This was already done for the combinations
with Ctrl but not yet for the plain cursor keys.
The unshifted shortcuts are easier to type, and also less confusing in
my eyes. Putting them first means they get shown in the help lines,
and get listed first in the ^G help text.
(I would also like to put ^- first instead of ^_ (because the latter
is hard to see when using the default inverse video for shortcuts),
but on several terminal emulators Ctrl+- reduces the font size.)
Put all the movement keys together, in order of ascending stride.
Also, move the Undo/Redo keystrokes further up, so that, when the
user has a somewhat wider terminal than the usual 80 characters,
these keystrokes will be shown -- they are far more interesting
than the ^Y and ^V ones, for which PgUp and PgDn can be used.
Since all lines can be partially scrolled off the screen now
(except for edittop, which is forthcoming), the maxlines global
variable and its computation mechanism are no longer needed.
These improvements will eventually make do_home() and do_end() take
parameters. Since the global function lists can hold only functions
without parameters, preemptively add do_home_void() and do_end_void(),
and make the global function lists use them.
The platform's default char type might be signed, which could cause
problems in 8-bit locales.

(The variable 'pletion_line' is not conditionalized with this option, as
it would become messy. The compiler will probably be able to elide it.)
When using --enable-tiny, it is not possible to use --enable-wordcomp,
because the word completion function uses the undo system.
Executing the 'complete_a_word' function will search from the start
of the current buffer for entire words that begin with the fragment
that is before the cursor, and will complete this fragment to the
first word that is found. Each consecutive call of 'complete_a_word'
will search for the next matching word and will complete the fragment
to that. By default the function is bound to the ^] keystroke.
