Could you please explain what do you mean by ``will not be deleted'',
and why you think it's a bug?  The `echo' commands overwrite
mh-loaddefs.el, don't they? which is akin to deleting the (old) file,
right?

Anyway, of Emacs fails, then Make will stop and announce the error;
therefore I don't see why you (evidently) want an additional
manifestation of the problem.

What am I missing?
