It was originally on a separate file, but I thought, and still think,
that it should be in info.el.  I don't see any significance in the
fact that this will be used for manuals that come with Emacs, as those
are quite numerous.  E.g., on my system, Emacs manuals are about 1/4th
of all the installed manuals, and I have a lot of Info manuals other
than Emacs and no Info manuals that come with ELPA packages.
