Hmm, I suppose this has something to do with the fixes for bug #16604 [1].
Those were not supposed to affect the behavior for -reuse-previous=off
cases, which yours should be since there's an "=" in the \c argument.
However, after poking at it for a bit, I have a theory: are the
service-file entries that aren't being honored overridden by variables
from your environment (PGPORT etc)? I think that patch may have
unintentionally changed the relative priority of service file entries
versus other sources of default values.
