The names are there, but not the signatures, and there isn't even a
minimal description of the arguments.  That is too radical, IMO.

The manual is also for people who want to understand what the code
they look at does.

Then why do we have the ELisp manual at all?

I'm really unhappy about deleting that from the manual.  Would you
mind if I added back some minimal docs?
