To clarify, this isn't a java regex library, but rather regexps used to
match function names inside java language files when generating diffs.
The regex library itself is the POSIX regex routines provided by libc.
PCRE syntax is nice, but we don't want to require it for every build,
and it's important to have the same syntax everywhere (so that, e.g.,
your config from one build works on a different build).
