Looks good, committed. It might've been a tad more efficient to return
the StringInfo buffer directly from pgp_armor/dearmor, and avoid the
extra palloc and memcpy, but this isn't performance critical enough for
it to really matter.

Are you planning to post the main patch rebased on top of this soon? As
in the next day or two? Otherwise I'll mark this as "Returned with
feedback" for this commitfest.
