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.

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.

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).
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.
