pg_regress gripes

A couple glitches to work out in pg_regress:

1. 'make installcheck' fails if PGPORT isn't set in environment.  Should
omit '-p $PGPORT' options from program invocations unless PGPORT is set.
Actually, I think you should omit -p period; the programs are perfectly
capable of reading PGPORT from the environment for themselves.

2. I get this behavior:

test hash_index           ...  ok
test misc                 ...  FAILED
test select_views         ...  ok
test alter_table          ...  ok
test portals_p2           ...  ok
test rules                ...  ok
test foreign_key          ...  ok
test limit                ...  ok
test plpgsql              ...  ok
test temp                 ...  ok

=================================================0 of 75 tests passed, 0 failed test(s) ignored.
=================================================

(The misc failure is from a bug in some other stuff I'm working on;
I show it just to illustrate that pg_regress's helpful totals are
completely incorrect.)  I presume the output is more useful for you,
which probably means that echo behaves differently on your platform.
Possibly should be looking for '\.\.\. *ok' and so on?
