> The next-error-select-buffer documentation states that “the selected
> buffer becomes the source of locations for the subsequent invocation of
> ‘next-error’ or ‘previous-error’.” However, it is not the case for the
> following:
>
> 1. Go in a fresh next-error capable buffer (not *grep*).
> 2. Grep for something.
> 3. M-x next-error-select-buffer *grep*
> 4. M-x next-error
>
> The buffer of 1 (not *grep*) is the source of locations instead of
> the expected *grep*.
>
> This is because although next-error-select-buffer sets the variable
> next-error-last-buffer, it is not used in this case: When next-error
> calls next-error-find-buffer, next-error-buffer has no buffer-local
> value yet, so condition 2. in next-error-find-buffer (that
> next-error-buffer has no buffer-local value and the current buffer is a
> next-error capable buffer) is true, and the function never even checks
> next-error-last-buffer.
