Preventive maintenance in advance of pgindent run.

Reformat various places in which pgindent will make a mess, and
fix a few small violations of coding style that I happened to notice
while perusing the diffs from a pgindent dry run.

There is one actual bug fix here: the need-to-enlarge-the-buffer code
path in icu_convert_case was obviously broken.  Perhaps it's unreachable
in our usage?  Or maybe this is just sadly undertested.
