I haven't looked at etags, but here's a patch for dired.el that will
add next-error support.  That will support find-grep-dired,
dired-do-search, and all other dired-mode usages.  There's two issues:

1) by default, most users will probably not want this next-error
   support so I added a variable dired-next-error-support that's nil
   by default.  This is my conjecture so I may be wrong.

2) I am not sure of the right way to move negative distances in
   dired-mode, since not every line is a file.  I reuse the
   dired-goto-next-nontrivial-file function for forward motion and
   ignore negative distances for now.  I could write my own, but was
   wondering if something already existed for negative motion.

Please comment and I hope this can make it in Emacs eventually (it's
not ready as it is).  I am attaching a context patch.
