Is it cygwin1.dll or rlogin that is trying to convert $USER into a
determination of a mail spool directory?  If it is cygwin, we should
probably patch cygwin to ignore or modify any $USER containing
backslash, rather than trying to treat it as a subdirectory.  That is,
tilde expansion will treat '~Bliss/law' as the username 'Bliss' with a
subdirectory 'law', rather than as the single username 'Bliss\law'.  I
suspect the bug is in rlogin rather than cygwin, though, if you are only
getting the message when trying to log in with rlogin, and since the
message is about a mail spool and not about a $HOME.

Meanwhile, I still wonder why the error message is printing 'Bliss/law'
as the problematic string, when it appears that the reason the warning
appeared is because rlogin was using $USER literally as 'Bliss\law'.  We
may still need to find and squash a cygwin bug that displays the message
incorrectly.
