Nice to be trusted... :-)  Still, the above should have been
- Make handling of /foo\bar equivalent to \foo\bar.  (Christopher Faylor)

This means that any path with a \ will be treated as a Windows path (off
the current drive).

You should be able to use Windows paths as-is even now.  What I meant were
corner cases, e.g., /foo\bar now means c:\foo\bar, and not /foo/bar (as it
did in pre-1.3.19).

You can keep '\' as a separator, as long as you're aware that under
Cygwin, \foo != /foo.
