I didn't say anything about C-x C-v. I said that a prefix key followed by C-h
doesn't always show the prefix key bindings.

FWIW, I suspect that the OP might have meant `C-x v', which is a prefix key and
for which C-h does work: `C-h v C-h'. But there are other prefix keys for which
it does not work.

Some users, such as myself, explicitly bind C-h in isearch-mode-map so that C-s
C-h does show the C-s bindings. RMS does not want that behavior for Emacs,
however.
