Re: next-error-last-buffer

[Richard Stallman]

    A less intrusive (and hence less complete) solution:

    - Create a new compilation-last-source-buffer variable.
    - At the end of next-error, set this new variable to the buffer just being
      displayed.
    - at the beginning of next-error check compilation-last-source-buffer:
      if it is equal to current-buffer, then don't consider this buffer as
      a "compilation" buffer (i.e. ignore its next-error-function).

This might be good.  We can at least try it.
