Awesome!  I have some hacking time next week, and I'm looking
forward to rebasing my branches onto your changes to see whether
we now have the speed required to finish my syntax highlighter.

More patches to alien?  Or a lua extension in C? (Sorry, I haven't
spent the time to become familiar with that part of the code, so it's
likely these are stupid questions).

That's not strictly true.  I was able to get backward search working
with rex_onig, although I don't doubt that there was an attached
performance penalty because of the hacky way I did it.
