# NOTE: This is not actually used yet.
#       Consumers of this function are getting it from actions-lib/gha_functions.sh until we can DRY the consumers out
#       This will require one consumer to import a commit message and dequote it for all other users which is tricky
#       due to the potential presence of both ' and " in commit messages
