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.
Only the basic colors (like red, blue and yellow) can take the prefix
"light" or "bright", not the extra colors (like pink, lagoon and lime).
This fixes https://savannah.gnu.org/bugs/?60674.
Bug existed since version 5.0, since the extra colors were introduced.
The "^_" has always been poorly legible (the underscore melting into
the bottom of the terminal) and difficult to type (Shift+Ctrl+minus).
The "^/" is both more readable and easier to type.
In terminal emulators, "^/" is shown, but on a Linux console "^-",
as ^/ does a backspace in the default console key mapping.
Also, allow using "^-" when rebinding ^_ in a nanorc file.
This addresses https://savannah.gnu.org/bugs/?57393.
In many places a carriage return is not valid whitespace and should
thus not be colored as such. In some of these places a vertical tab
or form feed is maybe valid whitespace, but it would be ugly or even
wrong to color them because they are not part of the subsequent
comment or keyword.
This fixes https://savannah.gnu.org/bugs/?60456.
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.

Bug existed since version 5.0, since --bookstyle was introduced.
And mention that a background color does not work on libvte before 0.55.
To find out the version of libvte on your system:
ls -R1 /usr/lib | grep libvte | grep 00 | grep -o "0\..."
The user had better avoid using the keystroke in a macro, but
when typing directly at a responsive machine there is no problem,
M-[ is a perfectly valid and recognizable keystroke.
This fulfills https://savannah.gnu.org/bugs/?58820.
The modifier has to come before the foreground color name, separated
by a comma, and after 'bold,' (when present). This has no effect on
terminals that are incapable of cursive text, like the Linux console.
This fulfills https://savannah.gnu.org/bugs/?56525.
After a year or so, when people have had time to convert their syntaxes
to use 'bold' and/or 'light' instead of 'bright', we can drop this
colorizing, and still later stop recognizing 'bright' altogether.
The name 'bright' does not fit its effect (often bolding the typeface),
so better discourage its use.
Furthermore, colorize 'bold' and 'light' also for interface colors.
This makes it possible to avoid the misnamed prefix "bright". It is
misnamed because (on current terminal emulators, when the brightening
of bold is switched off) it just makes the typeface bold, not the color
brighter. The prefix "light" will now only make the color brigther,
and the modifier "bold" will just make the typeface bold (on terminal
emulators, when the brightening of bold is switched off).
On a Linux console, which is not capable of bolding the typeface,
"bold" will brighten the color.
This fully fulfills https://savannah.gnu.org/bugs/?58503.
The prefix "bright" will continue to make the color brighter AND/OR
make the typeface bold (depending on how the terminal is configured
and on its capabilities), but the prefix "light" will just make the
color brighter (if the terminal can do that).
The prefix "bright" continues to do the same as what it did before,
to not change the appearance of user-defined syntaxes. And having
an option to change the meaning of "bright"... would be confusing.
This partially fulfills https://savannah.gnu.org/bugs/?58503.
A long option should describe what it does, not vaguely hint at it.
Also, in several places of nano's code we deal with actual temp files,
and then having a flag called TEMP_FILE that doesn't have anything to
do with temp files is somewhat confusing.
Since ^@ is rebindable too and also a synonym of ^Space, it makes
more sense to allow the user to specify ^` instead, as it is an
unshifted keystroke on US keyboards.
Also, color ^` as valid in a nanorc file, and color ^` and ^@ in
the help viewer.
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.)
Nowhere does the manual say that nanorc keywords are case-insensitive,
and none of the examples use uppercase keywords. So, simply consider
uppercase keywords to be invalid. This will later allow nano to use
case-sensitive comparisons, which are slightly faster.
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.
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.
