Thanks, but I think the documentation that accompanies these changes
should be augmented/improved:

  . next-error-select-buffer should be documented in the Emacs manual
  . the doc string of next-error-select-buffer should be expanded to
    explain the effect of selecting a buffer.  The current text is
    quite cryptic, IMO: "set it as the last used."  The meaning of
    "last used" in this context should be explained.
  . next-error-find-buffer-function should perhaps be mentioned in the
    Emacs manual and/or the ELisp manual.
  . the doc string of next-error-find-buffer-function should describe
    the arguments with which it is called, what possible values it can
    return, and the meaning of each returned value.

TIA
