I found a nicer solution with some help from Stackoverflow:

    git config --global alias.format-patch-repo '!git format-patch
--subject-prefix="PATCH $(basename $(git rev-parse --show-toplevel))"'

This adds an alias that automatically adds the folder name of the
repository. It can be used with

    git format-patch-repo HEAD^

If you only work in one directory, an alternative is to set the
format.subjectPrefix option in the repository.

Best regards

Christian
