Yeah.  You may even be able to set the flag from within
the add_setshow_... functions and friends.  The flag could
mean "this show command shows something that is settable
in some way" (or the reverse).

I think we shouldn't allow ourselves to broadcast bad design
when it's easy not to.  The function Michael touched is within
gdb/cli/cli-setshow.c.  I'd prefer to keep this and the other
core command files clean of specific knowledge of 
any specific commands their clients register.

I notice that "info set" is basically an alias of "show".
Does the change make sense in the context of "show",
or should "show" keep showing everything showable under
the show command?  "show foo|bar|..."
