I am aware of UNIX's semantics.  But the submitter of pr 15419 has a
situation where the behaviour of ftp(1) parsing
ftp://somehost/private/foo/blah.tgz as
        connect to somehost
        cd private
        cd foo
        get blah.tgz
doesn't work due to permission issues.  (If ftp did "cd private/foo" instead
of "cd private ; cd foo", it does work).

I'm not sure which ftp server implementation caused the problem.
Since it was a problem, and it wasn't immediately apparent to the
PR submitter how ftp(1) was triggering the problem, I decided to
document how ftp(1) parses the ftp:// URLs which may have made it
more obvious to what was causing the problem.
