For reference, here are the steps:

   ;; 1. If one window on the selected frame displays such buffer, return it.
   ;; 2. If next-error-last-buffer is an acceptable buffer, use that.
   ;; 3. If the current buffer is acceptable, choose it.
   ;; 4. Look for any acceptable buffer.
   ;; 5. Use the current buffer as a last resort if it qualifies,
   ;; 6. Give up.

How about a `next-error-priority' which can be numerically:

* local (each position refers to the file itself) = 0 (occur)
* finder (each position refers to other files) = 100 (compile, grep)
* or can be set by the mode to something else

Then (1) can become "if one window on the selected frame has the highest
priority, return it."
