Key description and fast typing are two separate issues.  Mnemonics is
yet another, third, issue (and assigning mnemonic value to 'm' in C-m
is generally unusual, IME).  I don't think these additional issues
should affect how we display C-m/RET _everywhere_ in our docs.  E.g.,
would you propose to use C-i instead of TAB?
