Re: M-g in dired

[Richard M. Stallman]

    BTW, there is a bug related to key suggestions: `M-x next-error RET'
    typed in a dired buffer suggests the key binding `M-g n' even though
    `M-g' is not a prefix key in dired buffers.

That seems like a bug.  where-is-internal should never suggest a key
which isn't really bound to the desired command.

ISTR there is code in where-is-internal that tries to verify this.
If so, that code must now be broken.  I am overwhelmed now; could
someone please try debugging this?
