Just in case anyone actually sets out to do this: please handle the
SHELL variable: If SHELL is set, use it instead of COMSPEC and the
switch should be '-c' instead of '/c'.  This will allow folks to use
shells other than COMMAND.COM.  Of course if you're exec'ing a '.bat'
file then you may want to use COMMAND ;-)
