It does get restored, but the code only has one level of restoration, so
the recursive calls overwrite it. Who's going to do multiple levels of
edit-and-execute-command?
If you want to run multiple recursive versions of edit-and-execute-
command, you should be savvy enough to get out using ^@ (control-shift-2),
right? :-)
