| 1 | //! `roots.worktree-update`: `git ents setup` sets |
| 2 | //! `receive.denyCurrentBranch=updateInstead` on the local repository, so |
| 3 | //! the integration-test-harness case — an external push landing on this |
| 4 | //! repository's own checked-out branch — also updates the working tree, |
| 5 | //! rather than the ordinary git behavior of refusing such a push outright. |
