I have been trying to make the generic exporter do fontification (bold,
italic, underline, etc.) and have fairly successfully managed to do this
by cargo-culting the code in org-latex.
But I've run myself on a rock. I can't figure out what the various
matches are that you get when you match org-emph-re. There are at least
5 matches, and some may be empty, etc. I don't /believe/ these are
documented anywhere (or I didn't find the docs).
Can anyone tell me what (match-string x) will be after a (string-match
org-emph-re string) call? Or tell me where to look to figure it out?
If so, I think I can get the fontification to work for org-generic-export.
(also, emacs-lisp question --- is there some way to /clear/ all the
registers for MATCH-STRING? When I have been doing this, I have
occasionally had troubles where match-string outputs from previous calls
to string-match seem to "bleed through.")
thanks!

The match groups are now documented:

You always need to check if there is actually a match by checking the
return value of the call. If there was a match, then you can rely on
the group. If there was no match, the groups bleed through
(when (string-match ...)
;; here you can rely on the groups
)
(when (re-search-forward "..." ...)
;; here you can rely on he groups
)

Thank you very much, Carsten. This is brilliant. With this information
I hope to be able to improve the org-export-generic substantially.
Best,
