Answer: 
AFAIK, `diff-hl` (available in your friendly GNU ELPA archive) works fine with both `nlinum-mode` and `linum-mode`, except when they both use the same margin (so you'll want to set diff-hl to either not use the margin, or to use the other margin).
[`git-gutter-fringe-plus`](https://github.com/nonsequitur/git-gutter-fringe-plus) works with `linum-mode`. Unfortunately, it doesn't work if you run Emacs in a terminal, but if you run Emacs graphically it should be a good solution.
