  I don't see the point of your patch.  You change the meaning of an
established target (show-options) to mirror that of another existing
target (supported-options-message), and re-introduce most of it's old
meaning under a new target (describe-options) while omiting part of it

  First of all, it is quite useful to know which options are enabled
by default, both as a guide of what's probably better tested, and as a
debugging tool for package developers.

  Second, this is a change of a user-visible (and documented) target
to something that is already available.

  If you want show-options to include which variables to set to select
options (and possibly a pointer to the relevant section in the guide),
then add that, don't remove useful information.  Or say what you want
added and I'll do it.
