Re: make mostlyclean

[Richard Stallman]

    In src/, `make mostlyclean' removes (amongst other things)
    "bootstrap-emacs", but it does not remove "emacs-22.0.91" (sans build
    number), which is a hardlink to "bootstrap-emacs". Should it not
    delete that file as well? It is the biggest file in src/ by some
    margin in my build tree.

I think this is correct.  If you build Emacs again it will get a new
number.
