git rev-parse master

This reproduces with a folder simply named ?.

I followed the steps on Windows 10, and could not reproduce the problem. Clicking undo deleted the file out of the ? folder.

This is weird, it looks like git clean is behaving differently depending on whether a directory with a question mark in the name is committed or not. If it's not committed, then something like git clean -f -q -- /Users/sean/Documents/Projects/testing/?/keepme does absolutely nothing, but as soon as I commit keepme and add a different file, then something like git clean -f -q -- /Users/sean/Documents/Projects/testing/?/keepme2 works.

Starting over, if I create a new test repository and then create a directory named test with a single file in it, git clean works just fine even without the directory being part of the commit history.
