Wonderful. Thanks for that.  Now I have renamed my symlinks to
~/.wine/drive_c and mnt/d so that they are no longer one letter, and
regedit works as it should!  All this trouble over a stupid directory
name..  Although I do understand why and how it works, now..  That is
extremely annoying, but since regedit is the only wine program that I
know of that uses /? it's not too big of a deal..
