Cool!  I wonder if a GLOBAL property CMAKE_PCRE_DEFAULT would be
appropriate at some point, after PCRE is proven.

What is odd?  MATCH matches the 1st match.  REGEX REPLACE replaces all
the matches.  It's odd that they're not parallel, but they're not odd
notions in and of themselves.

Dunno there.  I'm not seeing any downside to PCRE, so long as it's
disambiguated from CMake's current regexes.
