When one call describe-mode from *Bookmark List* buffer, the 
displayed documentation for the Bookmark Menu major mode displays 
an incomplete hard-coded keymap: The useful key / 
(bookmark-bmenu-search) isn't listed. I propose to rely on 
derived-mode-make-docstring to put the mode's keymap in mode 
docstring and to remove the currently hardcoded keymap 
description.

That's definitely a step backward, IMHO.

Just add `/' to the list.

A mode's `C-h m' documentation can, but need not,
list all of its key bindings.  (It can also tell
users that they can use `C-h b'.)

But more importantly, it should describe the mode,
not just punt to say that it inherits from its
parent.

The doc of `derived-mode-make-docstring' should,
and I think does, make clear that it provides only
rudimentary, fallback help in the (hopefully rare)
case where there is no other such help.

 "Construct a docstring for a new mode
  if none is provided."
  ^^^^^^^^^^^^^^^^^^^

It doesn't say that it's a good idea to not
provide a doc string for a derived mode, and to
instead use this to construct one.  Thank goodness.

Providing a doc string is normal.  Not providing
one is to be avoided, and IMO, is a bug from a
user point of view.

There's little excuse for copping out and not
providing a doc string.  There's even less excuse
for doing that for a mode's doc.  And there's still
less excuse for _replacing_ hand-written help with
such a poor, generic, robotic fallback.

Please just do the right thing, adding the help
you think is missing.  And provide whatever other
manual updates you think might help.


[To be clear, this doesn't affect me or my code.
Bookmark+ doesn't use the mode help provided by
vanilla bookmark.el.  I'm just expressing my
concern for vanilla Emacs here.]

Thanks.

As Drew points out, there's no need to show the entire set of
commands, so I just added '/' to the list.
