But is it such a bright idea to break it for everybody?  It's obviously
not a problem for non-domain, single-user systems.  And I guess
companies which set db_separator to "\" and db_prefix to "always" don't
care for this detail.  But in other companies with lots of login
domains, you have a potentially huge number of users working on machines
in another domain and the separator char would be present quite often.
