It's not as simple as it sounds. What if there's already a file called "stuff.txt (other guy's version)"? There's lots and lots of edge cases. You basically need a function that can always return an appropriate but not-already-existing filename.
I think graceful file conflict resolution will be an essential part of gitdocs and we will work to handle these edge cases as best as we can. Thanks for bringing it up.
Although, if I'm reading this correctly, the logic isn't quite right. It uses the timestamp of the time when the conflict is detected, when it should really use the conflicted file's last-modified time, or maybe the timestamp of the conflicting commit.
