The table is a bit redundant with the s-exp representation and I'm not
sure we want to spend all this time&space printing out a large keymap,
but maybe we could use the `help-fns-describe-variable-functions`
mechanism to add a one-liner that can be clicked to get to the
keymap-specific description, a bit like Custom vars have a "You can
customize this variable" link.
WDYT?

[ There is also something to be said to spice up `describe-keymap` so it
  can be used to *modify* a keymap.  But that comes with many more
  difficulties (the main one being how to save those modifications so
  they survive a restart).  ]
