    This makes me wonder if this should be a separate next-error.el file,
    instead of a patch to compile.el...  That way we don't have to load
    compile.el, and the code presents a standard interface to other
    modules.  What do you think?  If you like next-error.el, I can write
    that up.

We certainly do not want a separate file for such a small function.
Perhaps we could put it in simple.el.
