Change GIT_EDITOR environment variable for msys.
Change GIT_EDITOR environment variable for msys.

Previously, I set the `GIT_EDITOR` environment variable but **did not**
supply the `-f` flag. This lack causes the editor to return **before**
making any changes to the commit message. Supplying this flag as part of
the environment variable corrects the issue.
