Oh, didn't know about that.  Hm...  Yeah, I guess it should do the
trick.  But it's not included in the tarball, I think?  Which was the
request, and I'm still sceptical about doing that, because it looks
pretty dangerous.

That's sort of my point -- there's a ton of software out there that
doesn't work unless you install it first.  Emacs is not one of those, so
people think they have to install it to use it.

I wonder whether it'd be practical to put a "Really install? You don't
have to" in the "make install" target.  Probably not.

I think what most people who're futzing around with Emacs git would want
is just to have a target that makes some symlinks from /usr/local/bin
(or whatever) to the current build directory so that emacs/emacsclient
lands in $PATH.  I don't think the size of the source matters most, so
my guess is that few people delete the source tree after "make install".
