7.3 pg_ctl anomaly

When I run this command in 7.3,

    pg_ctl -w -o "-p 15432" start

it successfully starts the database, but the -w flag doesn't seem to
notice the successful start and continues to wait until finally
saying "postmaster does not start" and giving up.  Problem is,
postmaster started fine and continues to run fine even after pg_ctl
says it didn't start.  Here's an example session:


$ pg_ctl -w -o "-p 15432" start
