LEDIT on MIT-EE

[JIS at MIT-EECS]

Is broken as follows:

If you get an error while lisp is reading from the _LEDIT file, the file
object is never closed (even if you ^G out of the error break). So the
next time you try to read something from the ledit buffer into lisp, emacs
blows out trying to expunge the old _LEDIT file, because the lisp still
has it open. Apparently someone isn't unwind-protecting the file object
so it gets closed. A temporary (kludge^2) solution is for the user (me)
to GC before going back to the EMACS if I have errored out in the previous
reading.
