Allow the user to search in a help text with ^W and M-W.
Achieve this by not writing the help text directly to the screen
but first writing it to a temporary file and then opening this file
in a new buffer, and treating it specially: the normal file-reading
feedback is suppressed, the titlebar shows the headline of the text,
the cursor is hidden, and the menu is limited to just the up and down
movements and searching.
This fulfills https://savannah.gnu.org/bugs/?28994.

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.

In path names and file names, 0x0A means an embedded newline and
should be shown as ^J, but in anything related to the file's data,
0x0A is an encoded NUL and should be displayed as ^@.
So... switch mode at the two main entry points into the "file system"
(reading in a file, and writing out a file), and also when drawing the
titlebar. Switch back to the default mode in the main loop.
This fixes https://savannah.gnu.org/bugs/?49893.
(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.

Add the keycodes and routines to allow the user to forego setting the
mark explicitly (with M-A / ^6) and instead quickly select a few words
or lines by holding down Shift together with the movement keys.
(Some combinations with Shift are swallowed by some terminal emulators.
To work around some of those, the combinations Shift+Alt+Left/Right work
as Shift+Home/End and Shift+Alt+Up/Down work as Shift+PageUp/PageDown.)
Also, when a key string does not denote a Ctrl nor Meta nor Function key,
there is no point in assigning a keycode, because plain characters cannot
be used as a function shortcut.
And hard-bind the keys Ctrl+Up and Ctrl+Down to these functions.
Unlike the paragraph-jumping code, these new functions disregard
any indentation, treating only blank lines as separators. They
also do an automatic smart home when that option is set.
This fulfills https://savannah.gnu.org/bugs/?48291.
This allows the user to specify which other characters, besides the
default alphanumeric ones, should be considered as part of a word, so
that word operations like Ctrl+Left and Ctrl+Right will pass them by.
Using this option overrides the option --wordbounds.
This fulfills https://savannah.gnu.org/bugs/?47283.
Don't make it the responsibility of the executed functions to restore
the list of shortcuts of the edit window. Just detect whether another
menu was displayed, and if so, redisplay the main menu.
This allows for commenting or uncommenting a line or a bunch of lines
with a single keystroke (default binding: M-3). The characters used
for commenting/uncommenting are specified by the active syntax file.

Error messages about lock files should not get overwritten by purely
informational messages, only by alerting ones.
This fixes https://savannah.gnu.org/bugs/?47963.
If during startup there are multiple error messages, currently only the
last one remains and can be read. To improve on that, introduce a short
pause between error messages -- even if it's not enough to read them all,
at least the user will be aware that there are multiple ones.
This also causes a few error messages to beep that currently don't beep,
such as when a file is unwritable.
Since nano-2.4.1, reading in or pasting a large piece of text would put
the cursor on the bottom line, leaving only one line of the non-read or
non-pasted text visible. This is different from the centering behavior
of Pico, and somewhat disorienting, as you can't see "where you are" any
more in relation to the file as it was.
So now center the cursor whenever the read or pasted text is larger than
the screen, but don't center it when the text fits entirely on the screen.
(The latter avoids the effect of the screen jumping unnecessarily when
inserting just a few lines while the cursor is near the bottom.)
To achieve this behavior: default to focusing, and temporarily set it to
FALSE when the focusing effect is unwanted.
This fixes https://savannah.gnu.org/bugs/?47841.
Add a global variable, 'present_path', so that 'cwd_tab_completion()'
knows where the user is in the browser, so that it can try completions
against names in that directory instead of always against names in the
current working directory (where nano was invoked).
