Due to personal changes, GitHub changes, a desire of not wanting to continue to deal with mostly very low-effort contributions and not least a substantially lacking willingness to donate — despite hundreds of daily visitors and 25k+ stars — I've permanently moved this project to my personal Git instance, where it will live from now on:

Still available, still free, you can still contribute and are encouraged to by sending a git am style patch via email.
