I don't think there could be such a confusion (might depend on my code,
knock on wood), but if so, it would occur with '+' as well.  This
kind of confusion would not depend on the actual separator used.

The only reason I dislike backslash a bit is, that the backslash is
the escape char in the shell, so you would have remember every time
you type in such an account name to escape the account name,
DOMAIN\\username or "DOMAIN\username"
