I think the ability to use the regexp library to search non-contiguous
blocks of text is useful, and from my experience, even re_search_2
specifically is useful -- I've certainly wanted it in the past.  A
common example is where I'm reading a stream into a series of buffers
(or a ring buffer where there can be two non-contiguous parts), and
want to search for a regexp which I know will be shorter than the
buffer length, but might match at the break-point between two buffers.

What worries me is that this implementation means that the new regexp
is written in a way that makes it _hard_ to do this, requiring emacs or
whatever to simply always use a different implementation.

I hope this is the case, and that it's possible using their general framework.
