Thanks.

The idea sounds very good to me, but could you please post the output
of "help all" after applying the patch, so the improved results are
clearly visible?  It's hard to judge that based only on the code
changes, and at least I cannot easily build a patched version where
I'm typing this.

I suggest to simply move class_deprecated after no_class, so that the
compiler gives it a value.  We don't really care about the value in
that case, do we?
