Thanks!

md5.el doesn't exist in Emacs 21.  terminal.el indeed invokes /bin/sh,
but to fix that, the entire fragment which uses the shell should be
rewritten, since it invokes `env' etc.  I will look into that (your
diffs will not work if the user sets the shell to a Windows shell).
feedmail.el and mh-comp.el are okay, since they use /bin/sh in
conjunction with mailers which only work on Unix.

It is actually a bug to use explicit-shell-file-name unconditionally:
this variable only exists in the Windows version of Emacs.  So at the
very least, Lisp programs should see if it is boundp and non-nil
before using it, and fall back on shell-file-name if not.

Yes, but your change uses explicit-shell-file-name unconditionally...

Thanks, I'll take care of these gotchas.
