       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
