It is somewhat special-purpose; yes.  On the other hand, implementing it
in Lisp is a lot easier, and I guess I could envision people actually
using it for other things, too?  So I just put it in subr.el.  (But I
did not document it in the manual, because it does not seem to warrant
that.)

Pushed to the trunk now and the test case seems to work fine.

I'm not quite sure I'm reading this paragraph right -- I'm not sure what
"that" in "shouldn't be part of that" refers to here.  :-)
