I recently came across this cool feature in GHC under Windows, so
I guess it probably works in Hugs too, since Sigbjorn is involved
with both.

If you think about it, it isn't actually too difficult to work out that
a single letter directory name in the middle of a colon-separated path
is probably intended to be a drive letter belonging to the following
entry, and adjust accordingly.  I bet you could write a one-liner in
Haskell to do it.
