branch -m: update all per-worktree HEADs
When renaming a branch, currently only the HEAD of current working tree is updated, but it must update HEADs of all working trees which point at the old branch. This is the current behavior, /path/to/wt's HEAD is not updated: % git worktree list /path/to 2c3c5f2 [master] /path/to/wt 2c3c5f2 [oldname] % git branch -m master master2 % git worktree list /path/to 2c3c5f2 [master2] /path/to/wt 2c3c5f2 [oldname] % git branch -m oldname newname % git worktree list /path/to 2c3c5f2 [master2] /path/to/wt 0000000 [oldname] This patch fixes this issue by updating all relevant worktree HEADs when renaming a branch.
