+1. That's probably the single most annoying bit of behavior in pgindent.
Being a two-spaces-after-a-period kind of guy, it might bite me more
often than other people, but now that somebody else has brought it up...

AFAIR, no one has ever done a serious comparison to anything except GNU
indent, and (at least at the time) it seemed to have bugs as bad as
pgindent's, just different ones. I'm certainly open to another choice
as long as we don't lose on portability of the tool. But who will do
the legwork to test something else?

Probably the principal argument against switching to a different tool
has been that whitespace changes would complicate back-patching, but
I don't see why we couldn't solve that by re-indenting all the live back
branches at the time of the switch.
