git-publish --setup terminates with an exception unles run from git repository

[nyoxi]

When git-publish --setup is executed from an arbitrary directory that is not a Git repository it reports an exception and quits:

fatal: Not a git repository (or any parent up to mount point /home)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
Traceback (most recent call last):
