I agree. In fact, as I understand the patch it would also allow "-g r"
and "-g t", and that seems ugly too.

We don't have to have a short form for every long option - e.g. initdb
has several like --no-locale for which there is no corresponding short
form. I suggest we make the new options long form only, along the lines
Tom suggests.
