It now works in "*Customize Group*" buffers I tried, but the problem
is still there in some other similar cases.  For example, try

  M-x customize-apropos RET window RET

In the resulting buffer, the second 'H' still gets the same Invalid
widget error.  The same happens in a buffer created by
customize-faces.

Also, what about "M-x customize-browse"?  The buffer looks
differently, but don't we want 'H' to do the same there?

I've now made the doc string more detailed.
