Subject: 25.3; GUD not listed when describe-mode on source code buffer
Date: Thu, 10 May 2018 17:02:28 +0200

After 'pdb' Emacs function, and switch to the buffer where the source
code debbuged are, the Emacs function 'discribe-mode' doesn't say
anything about GUD and its (complex) commands available on this
buffer. I can still execute them (like C-x C-a C-b), but I need to go to
the manual to know wich commands I can run and what their key binding
are.

When I return on the GUD buffer, Emacs fuction 'discribe-mode' talk
about GUD buffer commands (like C-c C-b) but don't give anything about the
corresponding command on the code source buffer.

Tested with 'emacs -q'.

Neither dues `M-x gdb' and friends, apparently.  I've now included the
keymap at the end of the docstring -- some modes do, and some don't
(because `C-h b' will show you the commands anyway), but I think it
makes sense here.
