I think that highlighting is useful *only* in grep-mode, when
the cursor is not displayed in non-selected source window
(i.e. cursor-in-non-selected-windows is nil).  And highlighting
is pretty useless in `next-error' which selects a source window,
because in this case the location is indicated by the cursor.

But currently it's not possible to highlight the source buffer
only in `next-error-no-select'.  Perhaps a new argument should be
added to `next-error' and `compilation-next-error-function' indicating
whether highlighting is desirable and in what fashion (overlay flashing
delay duration, fringe arrow, etc.)
