If you switch to the buffer called " git blame for <filename>" (notice the leading space, you will probably see a usage/error message from git.

Maybe your git blame doesn't like the --incremental flag or the --contents flag. But the problem is that I'm not sure how to make emacs not hang.

process-send-region blocks when sending the file contents, since git isn't reading it. But git finishes, so emacs should be able to detect that there is no process that can read anything anymore.
