Many, many applications also require that backslashes be used in path
arguments (whether or not they're being executed via the "DOS" shell).

Interestingly, the _real_ DOS shell from several decades ago let you
change the "option" character from "/" to anything you wanted ("-" is
one correct answer), and the shell would then be perfectly happy with
forwards slashes in paths.  But, there were still plenty of
applications that whould choke on forward slashes in path
arguments. Apparently a lot of application developers were ignorant of
the fact that the system option character was configurable by the
user.

Thank Dog for the MKS toolkit.

One point to Microsoft on that one (they're still way behind).
