This approach has one problem: different rules in grep-regexp-alist
are not mutually exclusive, so information from different regexps can
appear in grep buffers from similar regexps. In the worst case
this can cause subsequent calls of `next-error' revisiting the
same source line several times for each of separate regexps.
If that can happen, it is a bug in compile.el.
It should never find more than one match on any given line.
