returns. Remove to carriage return ignoring hack introduced by

Fix pg_upgrade to cope with non-default unix_socket_directory scenarios.
It runs the regression tests, runs pg_upgrade on the populated
database, and compares the before and after dumps. While not actually
a cross-version upgrade, this does detect omissions and bugs in the
involved tools from time to time. It's also possible to do a
cross-version upgrade by manually supplying parameters.
