The regcomp() function from glibc-2.27 (and older) considers the
bracket expression ['-.] to be invalid -- mistakenly. Avoid using
any range expression in the relevant regex and instead enumerate
all acceptable characters.
This avoids https://savannah.gnu.org/bugs/?56766.
And generally improve the regex for coloring Perl variable names.
This fixes https://savannah.gnu.org/bugs/?56713.

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.
This addresses https://bugs.debian.org/932192.

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.
This addresses https://savannah.gnu.org/patch/?9801.

Some of these directives are now colored in their entirety, while for
a few others it's still just the keyword itself that is colored.

Using --zap or -Z on the command line, or 'set zap' in a nanorc file,
makes the <Bsp> and <Del> keys erase selected text (a marked region)
as they do in some other editors, and without affecting the cutbuffer.
This fulfills https://savannah.gnu.org/bugs/?54837.

Assume that 'print' and 'exec' are statements when they are followed
by whitespace, and are functions otherwise. This does not highlight
"print'x'" nor "print{x}", but these statements are poor style.

Also, don't partially color "..." as an operator, because it isn't,
and color also the unary operator "#".

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

When 'afterends' is set and Ctrl+Right or Shift+Ctrl+Right is pressed,
nano will stop at the ends of words instead of their beginnings.
