While looking at fe-auth.c I noticed quite a few places that weren't
bothering to make error messages localizable (ie, missing libpq_gettext
calls), and/or were failing to add a trailing newline as expected in
libpq error messages. Perhaps these are intentional but I doubt it.
Most of the instances seemed to be SSPI-related.
I have no intention of fixing these myself, but whoever committed that
code should take a second look.
