Does it make a difference if you run your git operations through cmd from the bash command line? If so, is there a simple way to automatically get the current windows path from pwd? If it's the same speed as native git running in a separate window (I think it should be), it might be worth coming up with some kind of script to do this automatically. Not sure how to get that working with using Linux tools within git, though (editing commit messages, diffing, etc). Also, how does file speed within the Linux environment (/home/username) compare to that outside (/mnt/C/whatever)?

Also, they _really_ chose a poor name for that executable; it should have been wsl.exe or some such, not bash.exe. At least lxss.exe isn't already in use by other software in my path...
