Re: next-error-last-buffer

[Richard Stallman]

    I tested this change, and it seems to work correctly with occur,
    i.e. it allows to continue visiting next occurrences from the same
    occur buffer where the current source buffer was visited from,
    even if it is not from the last occur/compile/grep.

If you switch to another source buffer that was last reached
through C-x ` from a compilation error, then C-x ` will get the
next compilation error, rather than the next occurrence.
At least, it sounds like your change would have that result.

I don't think that is the right behavior.
