Re: Key-binding clash between gnus and calc

[Richard M. Stallman]

    As me for another example.
    Gnus has been part of Emacs longer, so if either one has rights, it
    would be gnus.  However, gnus uses it only in gnus buffers, while Calc
    tries to use it globally.

I think Calc had better look for a more obscure binding for this,
or else leave it to users to make key bindings if they want one.
