Attack of whitespace pedantry

pgsql conventions (tabs, four-spaces-wide, etc) applied all around.

Also tried to fix some very tiny capitalization errors, auto-fill
problems, and some inter-block vertical whitespacing issues.

Long strings in repmgr.c were left intact, though. They are rather
numerous and are less of a problem than tiny bits of function calls
and comments wrapping over a line; the latter kind of problem has been
mostly fixed.
