Tweak a few more things in preparation for upcoming pgindent run.

These adjustments adjust code and comments in minor ways to prevent
pgindent from mangling them.  Among other things, I tried to avoid
situations where pgindent would emit "a +b" instead of "a + b", and I
tried to avoid having it break up inline comments across multiple
lines.
