This bug seems to date from the first day that `describe-mode' included
minor-mode information.
emacs -Q
Visit any *.el file, hit `C-h m', then search for `Transient' in *Help*.
The help for `transient-mark-mode' says this:
"...for example, incremental search, <, and >."
`<' and `>' here should be `M-<' and `M->'. The bug happens because
`help-mode-map' is being used to interpret `\\[beginning-of-buffer]'
and `\\[end-of-buffer]'. In the *Help* buffer, where the text is
used, the current keymap is being picked up, where these commands
are bound to `<' and `>'.
Note that the problem isn't manifested for something like `C-h f
transient-mark-mode'. In that case the bindings picked up are those of
the current buffer where the command is issued. If you do that in
*Help* then you get `<' and `>'. If you do it in *.el then you get
`M-<' and `M->'.

This bug still exists in Emacs 24.3.

Here's a shorter test case:
(progn
(describe-function 'transient-mark-mode)
(with-current-buffer (get-buffer "*Help*")
(revert-buffer)))
After answering "y", the `M-'s will go missing before the `<' and '>'.

Hm... well, after fiddling with this a bit more, I see that it's
describing all these minor mode bindings in the context of the buffer
you were in when you called the description command. I think that's
correct. If you have these commands bound to `<' etc in that mode, then
that is what the help command will say.
So the form above will give different results when run from, say,
*scratch* and from a special mode, and that's fine. Closing.

One of us is missing something, I think.
The recipe I gave was this:
emacs -Q
Visit any *.el file, hit `C-h m', then search for `Transient'
^^^^^^^^^^^^^^^^^^^
in *Help*. The help for `transient-mark-mode' says this:
"...for example, incremental search, <, and >."
And I explained the cause: The doc for `transient-mark-mode'
is being picked up after *Help* has become the current buffer.
That is not the correct behavior.
It is NOT being picked up from "the context of the buffer
you were in when you called the description command". That's
exactly what the bug is: it is NOT behaving as you claim it
is. It is showing you `transient-mark-mode' bindings for
`Help' mode, not for `Emacs-Lisp' mode, which was the mode
of the buffer where you hit `C-h m'.
This should not have been closed, or else I am truly missing
something.

I agree. I can reproduce this, and your explanation makes sense.

This bug was summarily closed today as "wontfix". Why?
No explanation; just closed out of the blue. Perhaps
the close was a typo on the bug number?
Please read the (short, simple) thread. Two Emacs developers
have confirmed that this is a bug, one of them after thinking
at first that it might not be (it was closed and then reopened).
Please reopen (and fix) this bug. Thx.

No, it was closed as wontfix on May 1st, 2016, then reopened after
some discussion.

I just removed the wontfix tag last night (since Lars obviously forgot

OK, thanks for doing that.
Sorry for misunderstanding the control message.

I can no longer reproduce this using the above recipe; the
`transient-mode-mark' docstring was changed in commit b99192fe24fc.
Do we have an up-to-date reproducer for this?

Not from me. I don't see the problem in Emacs 27.2.

OK, I'm therefore closing this bug report as unreproducible. If anyone
knows how to reproduce it, please write back and we can reopen the bug
report.

Does unreproducible mean that it never could be reproduced, or that it can no longer be reproduced?
If it was reproducible (which this was), and it no longer manifests, then it was _fixed_ (even if by accident), no?

AFAIU, it was reproducible, but it is no longer.
I guess fixed might be better, so feel free to change its status.
