	Allow git to run on an other user repository

	Reported by Anton:

	"Recent versions of libgit2 broke stagit for me due to the added opt-out
	GIT_OPT_SET_OWNER_VALIDATION configuration knob. My repositories are owned by
	root:vcs and I run stagit as another user which happens to be in vcs group but
	not the owner of the repository. Disabling the validation makes stagit work as
	expected again."

	Some notes:

	When using regular git it also provides a knob. This is due to a security
	concern in some cases, which is not applicable to stagit.

	git log somerepo

	fatal: unsafe repository ('somerepo' is owned by someone else)
	To add an exception for this directory, call:

	git config --global --add safe.directory somerepo
