Hi all, I have no idea how to debug this. As of git version 2.10.0 git hangs indefinitely when I run `git mergetool`, the result is the same if I run `git mergetool --tool-help`. The result is identical regardless of which version of vim I have installed, or where vim in installed. It is also the same if I remove my .gitconfig file. I am on Arch Linux, with all of my software updated to the latest versions as of this morning. git 2.9.3 and lower works perfectly. Any ideas? Thanks, Mike
