That is: do not silently return from parse_one_include() when the
given file does not exist, *and* return the filename (or pattern)
itself when it matches nothing.
This fixes https://savannah.gnu.org/bugs/?63446.
Bug existed since version 4.0, commit d3f0d32e.
This prevents an unwanted message when nano
is compiled with -fsanitize=undefined.
This fixes https://savannah.gnu.org/bugs/?63447.
Problem existed since version 4.8, commit 343f97b3,
since the --rcfile option was added.
"Cannot map name %s to <thing>..." was unnecessarily verbose and vague.
I have kept these strings unchanged all these years because I didn't
want to invalidate the existing translations. But now it's time to
harmonize things and simply say "Unknown <thing>: %s" for an invalid
function name, menu name, option name, and syntax name.
("No such <thing>: %s" is nice and snappy, but its translations often
are clumsy and longer and unclear.)
(It is a harmless leak, but LeakSanitizer is loud when it complains.)
After having determined that there is a menu name, first check that
it is valid, before processing the string or the function name.
This fixes https://savannah.gnu.org/bugs/?62991.
Problem existed since version 2.9.4, since string binds were introduced.
This makes more sense than letting the formatter and the linter depend
on ENABLE_COLOR (which maybe should have been named ENABLE_SYNTAX).
This fulfills https://savannah.gnu.org/bugs/?50080.
Most terminal emulators support a palette of 216 indexed colors:
the 6x6x6 color cube pioneered by Xterm. But as an index gives
little indication about what kind of color it produces, allow the
user to specify the color with three hex digits instead, one for
the level of red, green, and blue each, in the format #rgb.
One hex digit allows for sixteen values, but as there are only
six levels available, only 0, 4, 8, a, c, and e are significant
-- other values get reduced to the nearest lower one.
This fulfills https://savannah.gnu.org/bugs/?56445.

With --zero or 'set zero', nano will hide the title bar or the minibar
(whichever is active) and will use all rows of the terminal for showing
the text of the buffer. Only when there is an important message will
it be shown on the bottom row -- until the next keystroke.
This feature can be toggled with M-Z.
The feedback at startup ("Read nnn lines") is suppressed with --zero,
because it disrupts the fullscreen experience (and is hardly useful).
The "Reading..." message then needs to be suppressed too, otherwise
it creates an annoying little flash.
There are still some issues that need to be addressed:
* In the browser, when the highlighted item is on the bottom row, it
will get obscured by the prompt bar or the "Search Wrapped" message.
* In the edit window, when the search occurrence is on the bottom row,
it can get obscured by the "This is the only occurrence" message.
* When tabbing at a prompt shows possible completions, they are shown
a row too low.
In the beginning, the goal for nano was to be a drop-in replacement for
Pico. Pico did not know a Suspend command, so the ^Z keystroke needed
to be conditionalized on an option (-z or --suspend or the toggle M-Z),
just like the ^S and ^Q keystrokes (for stopping and resuming terminal
output) were conditionalized on --preserve.
But nano has abandoned full Pico compatibility since version 4.0. It
is time to unconditionalize ^Z as well. This should not be a problem:
Debian and Ubuntu have had 'set suspend' in their /etc/nanorc for years,
so a considerable portion of nano users have had ^Z enabled by default
for a long time, and no one seems to have complained.
If the keystroke bothers some user, they can unbind it in their nanorc.
They will still be able to suspend nano through the Execute menu: ^T^Z.

(Aaah, being able to define a keyboard macro
came in very handy when making this edit.)
This fixes https://savannah.gnu.org/bugs/?61331.
Bug existed since before version 2.2.0.
For consistency, these five names ought to start with "flip_", but
then the bindable functions would need to be renamed too, and that
would be annoying for the user, *and* it would create too many names
that start with "flip" -- it wouldn't be distinctive any more.
When it is not specified, it defaults to the value for 'titlecolor'.
When not using --minibar, I want the title bar to be blue (as that is
how I've always had it), but with --minibar, I want this mini bar to
be grey, as otherwise it reminds me too much of the prompt bar.
Also, colorize 'set minicolor' as valid in a nanorc file.
Because "lightnormal" sounds strange, and can have unexpected effects.
This fixes https://savannah.gnu.org/bugs/?60668.
Bug existed since version 2.9.5, since the name "normal" was introduced.
This reduces startup time by seven percent (when using the standard set
of syntaxes) when opening just one file that doesn't match any syntax,
and more than ten percent when opening multiple files. It takes some
extra memory, but... not wasting CPU cycles is more important.
This addresses https://savannah.gnu.org/bugs/?56433.
Now that a search match gets highlighted, the unsuspecting user might
think that the text is selected, because it is colorized the same way
as selected text. Avoid this by colorizing a highlighted search match
with its own specific color, black on yellow by default.
Now all toggle functions have the same name as their corresponding
long command-line option. Also, all names now indicate the effect
of the toggle when it is invoked from a default setting.
