I sometimes run microEmacs from the workbench, where it has the obnoxious
habit of locking up the system when you endcli after a spawn-cli.  Amiga
hack has the same bad habit.  The spawn-cli below fixes this problem,
though it is somewhat ugly.  As far as I know, this doesn't do anything
that will break the system; I'm sure I'll find out soon enough if someone
else finds such a creature :-). 

Those of you who don't run microEmacs from the workbench should probably
ignore this.  Those working on porting the latest Hack to the Amiga should
probably pick it up.
