I\'m a clumsy typist, and I don\'t use vi/vim very often, but I do use it for commit messages. However, if you type a wrong command while editing a commit message (:Wq
You should set vim to not detach from the shell and be in the foreground. You can do this with the following command:
git config --global core.editor vim -f
From the man:
-f Foreground. For the GUI version, Vim will not fork and detach from the shell it
was started in. On the Amiga, Vim is not restarted to open a new window. This
option should be used when Vim is executed by a program that will wait for the
edit session to finish (e.g. mail). On the Amiga the ":sh" and ":!" commands
will not work.
As mentioned in several posts vim is exiting with a exit code other than zero. You can fix it by explicitely setting the git editor to the full vim path:
git config --global core.editor /usr/bin/vim
If I remember correctly I fixed the issue by installing a homebrewed vim. Make sure your path is set correctly then.
