916b4d81d0 rcfile: add 'stripecolor' for changing the color of the guiding stripe 
The default is now simply reverse video, which works better than a
"loud" colored bar in an interface that for the rest is monochrome.

ae3ec1784d options: add --zap, that makes <Bsp> and <Del> erase a marked region 
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.

790f98560b syntax: python: do not highlight 'print' and 'exec' in Python 3 
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.

c524fbe6d0 tweaks: remove some ineffectual parts from header-line regexes 
Adding "[abc]*" does not restrict the recognized header line in any way.

Also, improve the header-line regex for shell scripts, because it should
