Benno Schulenberg 2a97cb9f41 bindings: allow to rebind ^/, even though it is synonymous with ^_
This fixes https://savannah.gnu.org/bugs/?57302.

Benno Schulenberg 4d77e0adbb speller: prefer 'hunspell' over 'spell', because it can handle UTF-8
Also, 'hunspell' is sensitive to the 'LANG' environment variable,
so that spell checking will take place for the language that the
user is using, instead of always for English.  (This is a behavior
change, and some people may not like it, expecting the spell check
to occur always for English, but... we'll see.)

Benno Schulenberg 576502a5c5 speller: when 'spell' is not found, try running 'hunspell -l' instead
This increases the chances that spell checking will work out of the box,
without any extra installing or configuration.

Benno Schulenberg ec9a11c761 display: do refresh the edit window when exiting from the help viewer
There are several cases (searching, replacing, spell checking, ...)
where exiting from the help viewer does NOT return the user to the
editing of the buffer.

This fixes https://savannah.gnu.org/bugs/?57295.

Benno Schulenberg 1c63bf0e38 bindings: the 'all' keyword should include the browser menu always
Also for the "universal" functions (like cursor movement) and the
special 'implant' function, the 'all' keyword should include the
browser menu.

This fully fixes https://savannah.gnu.org/bugs/?57280.

Benno Schulenberg f230c46e5e tweaks: drop the unneeded closing of descriptors when exiting anyway

the error code would try to close descriptors that are already closed,

that are still open.

Benno Schulenberg 2b9f06194f formatter: don't let output from the program pollute the screen
Run the formatting program outside of curses mode, so that any output
(complaints) that it produces will be on the terminal after exiting
from nano -- at least on a terminal emulator, not on a Linux VT.

This also allows the formatter to be an interactive program.

The disadvantage is that the screen flickers when typing M-F.

Benno Schulenberg a6dae403e6 formatter: accept the formatted result also upon a nonzero exit status
For a nonzero exit status of the formatting program, report on the

report failure when the intended program could not be run.

Benno Schulenberg 4281b6becb commands: rename 'fixer' to 'formatter', to be less misleading
The word "fixer" sounds too much as if the command would be able
to fix mistakes or correct errors.  Especially when seen next to
"linter", it sounds as if one does a syntax check and the other
fixes the found mistakes.  (Although the command might in theory
be used for this, it is not its intended purpose.)

Benno Schulenberg 3c695664ec tweaks: elide a function call for the plain ASCII case
When dealing with a plain, seven-bit ASCII character, don't bother
calling is_cntrl_mbchar() but determine directly whether it is a
control character.  Also reshuffle things so that we don't compare
charlen == 1 when we already know it is 1.

Benno Schulenberg fa88fcc8f2 tweaks: rename a function, and elide a parameter that is always NULL
After the previous change, all remaining calls of parse_mbchar() have
NULL as their third parameter.  So, drop that parameter and remove the

already too many functions that start with "parse".

Benno Schulenberg 95ae124891 history: don't wait when there is something wrong with the history files
Do not wait for the user to press a key when there is some problem

on the status bar.  The precise error message is stored and will be
shown on the terminal when exiting from nano.

Benno Schulenberg 022cc084a7 files: when opening a file for copying, it should NOT be created
Weird bug.  The first occurrence is probably never hit because the
existing file has been tentatively opened fourteen lines earlier,
but that looks superfluous: double work.  And the second occurrence
will not be hit because the temp file is unlikely to have disappeared.

Benno Schulenberg 7f8851caa8 statusbar: show only the first error message, with dots to indicate more
The old default behavior of showing the first three messages with a
long pause after each of them was annoying, and the final "Further
messages were suppressed" hid the relevant information.  So, when
there is more than one error message, just pause very briefly and
then add trailing dots to the first message.

This makes the 'nopauses' option a no-op.

For the three operations (justification, spell checking, and filtering)

too late to have any effect.

Benno Schulenberg f813fd0f4d rcfile: allow binding also F17...F24
For historical reasons the rebinding code allows binding F13...F16,
which on most terminals are typable with Shift plus F1...F4.  But,
at least on an Xfce Terminal, Shift plus F1...F12 produce F13...F24.
On a Linux console, Shift plus F1...F8 produce F13...F20.  So: allow
to bind the full shifted F13...F24 range.  It costs no extra code
and makes things more rounded.

Benno Schulenberg 78def852d1 mouse: make the clickable width of menu items more consistent
When there are fewer than four menu items, act as if there are four:
make their clickable width half the width of the screen.

Until now, when there were two menu items, their clickable width would
be the full width of the screen, which was overwide.  But when there
was just one menu item, its clickable width would suddenly be as small
as when the menu had the maximum number of items (12 for an 80-column
screen).  This was odd.

Also, slightly simplify another computation.

Benno Schulenberg b3ace4d8f6 tweaks: don't burden all menus with something meant for the WriteOut menu
The first_sc_for() function is somewhat costly, so avoid calling it
when it is not necessary.

Most menus have either so many entries that unbinding some keys does
not reduce the number of shown entries, or they have so few entries
that each entry already has space enough and will not profit from
having more room available.  But the WriteOut menu is an edge case.
Most translators don't use --tempfile and translate the key tags for
the WriteOut menu making use of all 17 positions that are available
for each of them.  This makes that when --tempfile is used, some of
those tags get truncated.  This is not so bad, because --tempfile is
normally not used.  But when it isn't used (when the discardbuffer
function isn't bound), the WriteOut menu should make full use of the
available width to avoid truncating any translated tags.

Benno Schulenberg 3644d51b97 new feature: a 'tabgives' command to define what the Tab key produces
The 'tabgives' command is syntax-specific and should be followed by a
string containing the character(s) that a single press of the <Tab> key
should produce -- most likely a single TAB or a small bunch of spaces,
but any string is allowed.  This overrides the 'tabstospaces' option.

When one wants to make sure <Tab> inserts always four spaces and never
a TAB when editing a Python file, one could add to one's nanorc:

  extendsyntax python tabgives "    "

where there are four spaces between the quotes.  And when one wants
to ensure, when editing a Makefile, that <Tab> always inserts a TAB
and never spaces, independent of what tabstospaces is set to, one
could add to one's nanorc:

  extendsyntax makefile tabgives "	"

where there is a literal TAB character between the quotes.

Benno Schulenberg d82c753ba4 rcfile: at terminating points, verify that a defined syntax is not empty
Whenever, in an rcfile, a command is encountered that is not part of a
syntax definition, a currently open syntax should be closed, but only
after checking that the syntax contains at least one color command.

This fixes https://savannah.gnu.org/bugs/?56501.

Bug existed since version 2.3.3.
