After a fresh install of Emacs and JDE on a new machine, I found that a
patch I thought I'd submitted some time ago is not in either JDE 2.3.5
or CVS.
The problem is caused by a change in behaviour of (expand-file-name ".."
dir) when dir is the root directory on a Windows drive. In previous
versions, the result was "D:/..", but in the current CVS code,
(expand-file-name ".." "D:/") returns "D:/", which is consistent with
what happens on *nix.
The following patch adds support for this in jde-root-dir-p, avoiding
some infinite loops:
