Yes, setting `next-error-last-buffer' locally in the compilation
buffer is not necessary with the current logic in `next-error-find-buffer',
but it could be set only for consistency.

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.

However, `occur-next-error' has its own problems that should be fixed
(it can't jump to multiple occurrences on the same line, it don't move
the point in the occur buffer like `compilation-goto-locus' does).
