Fix incorrect translation of minus-infinity datetimes for json/jsonb.

Browse Source 
Commit bda76c1c8c caused both plus and
minus infinity to be rendered as "infinity", which is not only wrong
but inconsistent with the pre-9.4 behavior of to_json().  Fix that by
duplicating the coding in date_out/timestamp_out/timestamptz_out more
closely.  Per bug #13687 from Stepan Perlov.  Back-patch to 9.4, like
the previous commit.

In passing, also re-pgindent json.c, since it had gotten a bit messed up by
recent patches (and I was already annoyed by indentation-related problems
in back-patching this fix ...)
