That sounds good.

But then the test should be more specific, and check if there would be a
file collision at the actual target location (with the name modified by
--program-transform-name, if applicable). If there's no collision (e.g.
Emacs ctags has a different name) then Emacs should install it.

Things are like this since more than a decade, and obviously distros can
cope with the status quo.
