So if my password is 'mba at 2foo' I have to do:

  smb://miallen:mba%402foo@server/c$/My Documents/seti at home.txt

I don't know. The URL decoding/encoding issue deserves work but a *lot*
of people have '@' signs in their password. Is '\' reserved? Maybe that
could be confiscated as a cheesy escape so we can do:

  smb://miallen:mba\@2foo@server/c$/My Documents/seti at home.txt

The language lawers would probably baulk at that one.

In hindsight it is compelling considering that damn '@' sign is the
whole reason we need to escape everything.
