Actually, what they support is whatever comes with the PCRE engine, and is
supported fully for matchText/matchChunk (AFAIK), whereas it seems like
replaceText only seems to support a portion of PCRE (although I could be
wrong).

True, but they *do* say "Revolution implements regular expressions
compatible with the PCRE library. For detailed information about regular
expression elements you can use with this function, see the PCRE manual at
<http://www.pcre.org/man.txt>."

And given the fact that regular expressions is a lengthy topic, I'm not too
surprised that they have not explained them in detail.

See above - I think they just want people to read the docs at pcre.org.
