Sorry that I was not clear enough: I understood this.

Kevin Rodgers provided a very nice roundup; can it replace this
cryptic paragraph?

Again, sorry that I was not clear enough.  On the contrary, I'm very
glad that finally, after more than a decade of bitching (while having
the working code available!) this feature is finally available in the
standard distribution.  A lot of thanks for including it!

So my "gaping hole" comment is due to my illiteracy.

All that I said is that

  a) I have no incentive to check whether the Emacs 21.4
     implementation is sane; and

  b) that my prior experience does not allow for a lot of hope in "a"
     (I remember there was *some* tricky stuff to code in imenu-go;
     but the only thing which immeditely jumps to mind is not related
     to return-back functionality; so, contrary to what I wrote, it is
     quite possible that there is no pitfall to avoid...).

Hope this helps,
Ilya

P.S.  Now, when End key finally does what users want, and there is a
      way to invert jump-to-tag, what about "the other stuff"?  What
      immediately comes to mind is "redo" functionality.  Is it
      available in 21.4?
