well... ok, but my patch was only designed to fix a specific bug, not
to add new features.

Then again, I am surprised this isn't already done.

This bit confuses me.

Are you saying that there are programs that call ftp as

ftp hostname 0

and expect it to turn port 0 into port 21 (returned by
getservbyname("ftp", "tcp"))?

I won't argue with this, but not convinced it is really required
either.
