Well, we always printed such types with outside parens, "PAREN"
just encodes this at OutputForm level. And reason is that
deciding when to omit parens is in general tricky, so we
otuput more parens than strictly necessary.

This is for consistency with other formatters. And adding spaces
by putting them as part of a name is asking for trouble.
