When re-using some part of the logic implemented in this plugin for my heirline config, I found a scenario where the repo's name would display an error message because the below command fails:

This commit fixed this issue in my config.

Tasks:

• Reproduce the issue
• Can the issue be reproduced on submodule names?

My workspace is a bit untypical. The root directory is not a git repo, but provides commands to automate git clone and make several interdependent projects with specified branch name of the repo of these projects.

For instance, when Imake ProjectC, which depends on ProjectA and ProjectB, the root repo will perform git clone and set proper CMAKE_PREFIX_PATH to compile ProjectC. However, the cloned ProjectA/B/C are not really submodules to the root repo.

At the moment, this plugins does not work in my workspace as it relies on .git and .gitmodules if I understand it correctly. I'm wondering if it's possible to make it also work for my case?
