Re: next-error-last-buffer

[Richard Stallman]

    goto-error: C-m, C-c C-c, M-o

Why do we want to define M-o as well as the other two?
That doesn't follow any general convention, it isn't more
convenient than C-m, and it isn't needed for compatibility.

    next-error-no-visit: M-n

Let's call that forward-error-message.

    previous-error-no-visit: M-p

Let's call that backward-error-message.

    next-error-file-no-select: M-}, M-N

I'd rather avoid defining M-N and M-P as different from M-n and M-p.
We don't need to do it; M-{ and M-} are equally easy to type.

Also, let's call these commands forward-error-source-file
and backward-error-source-file.

    next-error-file: new global command without keybindings
    previous-error-file: new global command without keybindings

What would these new commands do?
