No, I'm just saying that any additional features added to that function
should be considered carefully (to see whether that added feature is
worth the performance degradation).  And I don't think we should do
anything to "pretty it up" just because, if that has any performance
impact at all.

In a thing like shr, it's really the case of a death by a thousand cuts:
Each single improvement adds a slight performance hit, and then after a
couple of years you end up with something that's pretty, but completely
unusable.  (It's already too slow as it is.)  So I protect `shr-descend'
fiercely.  :-)

(But late, as always...  Sorry for not saying this before you applied
the patch; it would have been less work for all of us.)
