cindex: index full (40/64 char) hex blob OIDs

This future proofs the index against git auto-abbreviation
needing more characters as the repo grows.  It'll be useful for
joining against inboxes using dfpre.

As with emails, we'll continue indexing abbreviated blob OIDs
down to 7 hex characters so a SHA-1 git repo will have all
abbreviations of the OID from 7-39 hex characters in addition
to the 40 character unabbreviated form.
