[rfa] clean up output of "info set" command.

"info set" is meant to show the state of all "set"-able
debugger state variables, but it really executes each and
every "show" command in alphabetical order.

Several of these commands (notably "copying" and "warranty")
have no corresponding "set" command, are not "set"-able, and
produce a lot of output.  Especially "show copying" which
produces pages and pages of output.

This patch excludes "copying", "warranty", and "version" from
the output of "info set'.
