Right, and my point was that the issue is bigger than --compress.
For example, you get exactly the same misbehavior with
$ pg_basebackup --checkpoint=fast --format=t -d --pgdata=/var/tmp/dummy
pg_basebackup: error: must specify output directory or backup target
pg_basebackup: hint: Try "pg_basebackup --help" for more information.
I'm not sure how to solve the problem once you consider this larger
scope. I don't think we could forbid arguments beginning with "-" for
all of these switches.
