www_coderepo: allow searching one extindex|inbox

I'm not sure how to best make a UI for one coderepo to many
inboxes/extindices, yet; but at least allow a simple 1:1
mapping, for now.  This ensures /$CODEREPO/$OID/s/ can work
as effectively as /$INBOX/$OID/s/ when looking for emails
associated with a git commit.
