Because "C-x t C-h" is indeed undefined.

I think it makes no sense to tell users about C-h that shows the
available sequences when they already invoked a C-h command to ask
about a particular sequence.  So the patch below seems to be in order.
Also, "C-h K" will need a similar treatment (which is complicated by
the fact that it uses (interactive "k")).

Dmitry and Stefan, any better ideas?

Loos OK to me, tho maybe it should be the other way around: we should
bind it to non-nil around those places where we know it makes sense?
