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.
