Actually, it *should* support the full form of PCRE, since that is the
library that was used when the put it into the engine. The bugs you identify
above are all enhancement requests, so they are not representative of actual
bugs with the engine - in fact the only other two bugs I could find were
related to docs and not PCRE support at all.

So AFAICT we have a full and complete PCRE implementation here, with no
'real' bugs associated with it.
