Allow highlighting string delimiters differently.

bk2204 · guns · commit 65ec57dd7aaf · 2015-08-16T00:26:19.000-05:00
Some people prefer to highlight string delimiters in a different color
than the string contents.  Add a matchgroup for the delimiters and by
default highlight it the same color as the string.
