Known bugs in COMMAND.EXE

It has some problems spawning other programs.  (It doesn't work.)  Works
most of the time, but some programs really die hard...  Dunno why.

It does not pass the environment correctly to other programs (when it just
happens to call the program at all) when there are no variables set.

CD won't work with no arguments.

path searching is messed up.  Doesn't use current path, but uses path that
was passed to it...

When switching to a drive with no disk in it, it doesn't notice :-)

Command-line editing is REALLY slow, since it redraws each time.  This
will be fixed soon.

Interesting features:
---------------------

It skips a line or three between each command prompt.

CD works with a terminating \ on a path.  This probably won't be a problem,
but it is incosistent with MS-DOS.  It's nice to have since the TAB
completion adds the \ if you're completing a directory.
