String constants are probably the most common case.  They are the
frequently-asked-for case: for C comment blocks, bounded by /* and
*/, from faqs about regexps that I have seen.  (I don't think nesting
is actually respected in C comment blocks, but that's another story.)

I think it would be really useful to have this, even restricted to
string constants.  If I put this up as an RCR would there be
support, or have I overlooked somthing else? :-)
