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.

The fragment "\<\." can never match anything because \< matches the
beginning of a word but "." is not a word character.
Replace \< with \B (the empty string not at the edge of a word).

The list now includes all the Lua 5.3 functions listed on
https://www.lua.org/manual/5.3/#index.
Also, remove the coloring of just the library name, so that
only known library functions get highlighted.

Since a "0x" by itself is invalid. Also add word boundaries, so that
e.g. "00x1" (which is invalid) does not get partial highlighting.
Also remove some redundant backslashes from the strings regex.

Functions such as "io.close" should only be highlighted when the
package name ("io") is a word by itself, otherwise code such as
"fooio.close" gets unexpected partial highlighting.

Also, remove the coloring of special single-quoted strings as they
get recolored by the subsequent general string-coloring command.
And remove the coloring of all-uppercase words, as other editors
do not color those either.
It's better to color some invalid things as if valid than the other
way around. So, as strings can validly contain any number of double
quotes, just accept *anything* between the delimiting double quotes
and demand that the closing quote is followed by whitespace or EOL.
Since file-5.10 (end of 2011), libmagic identifies a C file in most
cases as "C source" instead of as "C program". Nano's magic strings
for some other files didn't match any more what file-5.32 currently
produces, either. So, they have been adjusted, new ones added, and
old ones deleted.
This fixes https://savannah.gnu.org/bugs/?52445.
The succeeding character was needed to avoid miscolorings due to nano
getting confused about starts and ends. But since commit 7ef5c532,
nano should be getting the starts and ends always right, so... undo
"temporary" commit 7b2ea405 from two years ago.
This addresses https://savannah.gnu.org/bugs/?51526.

The new option 'set selectedcolor' applies to marked text, to the
currently selected file in the file browser, and to the highlighted
match during interactive search-and-replace.
Extend get_softwrap_breakpoint() to break softwrapped lines on
whitespace when a flag is set. This flag is controlled by the new
rcfile option "atblanks". The '>' characters marking two-column
characters at the edge of the screen are disabled when it's on.
If get_softwrap_breakpoint() can't find whitespace in screen range, it
will break the line on the screen edge. (In this case, a blank can be
on the last column of the screen, but text can't, so that a blank on the
last column doesn't become invisible and possibly break the display.)
This fulfills https://savannah.gnu.org/bugs/index.php?49959.

Negative arguments of 'fill' are bright green since a few commits.
So now color all valid numeric arguments in that same style -- the
yellow was hard to see on a dark background anyway.
Also, color a zero tabsize as invalid.
Most of the keywords listed on the following URL are now highlighted:
http://php.net/manual/en/reserved.keywords.php
Also color single-quoted strings, and require that //-type comments
are preceded by whitespace or are alone on a line.

A tag begins not merely with a "<" but it must be followed by an
ASCII alphabetic character or one of "/", "!" and "?".
Further, color all the valid attribute names in red.
