Comment(by sjamaan):

 Here's another patch.  Alex said the irregex-match-valid-index? procedure
 ought to be exported, so that's what this patch does.

 I also added named submatch checking to irregex-match-valid-index?. By
 doing this, things like irregex-match-start-index now correctly accept an
 index-or-name instead of just a numeric index, so their behaviour now
 matches what the documentation says.

 It's also slightly more consistent because the index is now optional for
 all six irregex-match-{start,end}-{index,chunk} procedures, returning the
 full match (index 0) by default.
