For some reason the Romanian PO file contains a literal ^Q in one
of its translated messages -- currently at line 1984. This stray
^Q causes 'file' to classify po/ro.po as data.
Make such mistaken control codes easier to spot when using nano.
Constants that consist of a single character are valid too.
And a lone hash character on a line by itself also.

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.
A forward slash does not need to be escaped, and the backslash itself
should not be escaped: it serves to escape the star, to make it literal.
Also, remove a stray end-of-line anchor ($).
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.
Fortran and POV-Ray files are not found on any regular install of a
Unixy system nor in common software packages. People who want these
syntaxes will have to make a little effort to enable them.
Also, do not colorize the text between two stricken-through words,
do not colorize text immediately after an indented piece of code,
but do give color to a double trailing space.

In RPM 4.15, a number of new spec section features were introduced:
* %dnl - macro-engine level comments
* %elif, %elifos, %elifarch - 'else if' stanzas for conditionals
* %sourcelist - section for listing sources line by line
* %patchlist - section for listing patches line by line
* %generate_buildrequires - script section after %prep for
generating build dependencies
(Reference: https://rpm.org/wiki/Releases/4.15.0.html.)
An enhancement added in RPM 4.13:
* Sections for file trigger stanzas
(Reference: https://rpm.org/user_doc/file_triggers.html.)
As these are being increasingly used in Fedora and other distributions,
it's quite helpful to have syntax highlighting be up to date on handling
them.

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.)
Attribute names that are a part of another word should not be colored,

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.
For extensionless files, recognize C/C++ ones from the mode name
between the -*- marks on the first line.

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.

Bug existed since the Perl syntax was introduced,
in version 1.2.2, commit 70047eef.
Require that a comment starts at the start of a line or is preceded by
whitespace. This prevents most hash signs used for other purposes (and
what follows them) getting colored as comments.
This brings color to CakePHP template files, and to CUDA files.

The quotes of an empty string ('' or "") should be colored just like
those of a non-empty string, because otherwise the text *between* two
empty strings on the same line gets colored.
Add an extra rule to discolor triple quotes again to not make them
look like valid by themselves.
Also, remove six superfluous backslashes.

Adding "[abc]*" does not restrict the recognized header line in any way.
Also, improve the header-line regex for shell scripts, because it should

Plus one that automake recognizes: if. Color them only at the start
of a line. Also color all possible assignment sequences (surrounded
by spaces to not color the ones in shell fragments), and add some
comments.
Recognize not just "Makefile" but also "makefile" and "GNUmakefile".
And recognize these only when they are the full filenames, not when
they are the tail part of a longer name.
