H in info-mode as another describe-mode?

Hello Emacs folks.  Would you be ok with a change to make H in info-mode
do describe-mode (it's currently unbound), plus mention it up front in
the info.texi manual?

The principal reason would be to unify behavior between Emacs Info and
standalone Info; there are remarkably few discrepancies, and we can
eliminate this one, so my theory was, why not?  Although regular Emacs
users would probably think first of describe-mode (C-h m or whatever) no
matter what, there's no equivalent to that in standalone Info, and it
seems harmless to allow it.


(For the record, standalone info has swapped meanings of h and H a few
times, and it's currently the opposite of the above.  I plan to swap
them again for the next release to match Emacs.)

        with standalone Info.
