Attached is a patch to add other-window/frames version of the
`find-library' command.
BTW, after I added the two new commands and rebuilt Emacs (with just
`make'), I could not complete to them with `M-x find-library- TAB'. I
could only do this after loading the `find-func' library that contains
them. So I ran `make bootstrap' instead and then I could complete to
them as expected. I guess this means the autoloads had not been updated
with just `make'... which command should I have run? Bootstrapping
takes awhile.
