small patch for sftp urls

[Erik Bågfors]

Hi.  Here is a very small patch for sftp urls.

The problem is that is always wants you to have user in the path, as
in sftp://user@host/path but if you do "bzr push sftp://host/path" it
automatically adds the "user@" part for you.

What happens than is the following


bzr: ERROR: path u'sftp://foo/path' is not under base URL
u'sftp://bagfors@foo/path'

the following patch makes it so it just compares the "path" part of
the url (ignoring user, and host)
