Merge branch 'rs/maintenance-run-outside-repo'

"git maintenance run/start/stop" needed to be run in a repository
to hold the lockfile they use, but didn't make sure they are
actually in a repository, which has been corrected.

* rs/maintenance-run-outside-repo:
  t7900: fix typo: "test_execpt_success"
  maintenance: fix SEGFAULT when no repository
