What did you do before the bug happened? (Steps to reproduce your issue) 1. Run `git rebase -i next` with `--update-refs` or the git config setting `rebase.updateRefs = true` 2. Given `git-rebase-todo`: ``` pick fjr23j3 foo bar pick j3j413 bar bar ``` 3. Add a new update-ref line like so. ``` pick fjr23j3 foo bar update-ref refs/heads/devin/foo/bar/bar/bar/branch-new-name; pick j3j413 bar bar ``` `devin/foo/bar/bar/bar/branch-new-name` branch name does not already exist. The intention here is to create a new branch name at this point in the history (to create a stacked PR). 3. Complete rebase, see this output: ``` Successfully rebased and updated refs/heads/devin/foo-821-analytics-for-checkout. Updated the following refs with --update-refs: refs/heads/devin/edit-step-1-copy // <-- no semi refs/heads/devin/edit-step-2-copy // <-- no semi refs/heads/devin/refactor-foolytics; // <-- Trailing semi refs/heads/devin/foo-821-analytics-for-checkout; // <-- Trailing semi ``` 4. $ git branch devin/edit-step-1-copy devin/edit-step-2-copy devin/refactor-foolytics; devin/rename-logAnalyticsEvents; devin/foo-731-add-segment-tracking-to-tutorialfoocom devin/foo-736-lock-checkout-behind-a-query-param devin/foo-779-add-segment-events-for-all-clicksuser devin/foo-779-add-segment-events-for-all-clicksuser; devin/foo-808-button-to-re-try-failed-checkout devin/foo-808-button-to-re-try-failed-checkout; * devin/foo-821-analytics-for-checkout devin/foo-821-analytics-for-checkout; + devin/foo-828-add-sentry-to-tutorialfoocom devin/sort-tailwind-classes fix/crashing-on-falsy-amazonProductID main refactor-foolytics 5. After rebasing, paste a series of git push commands into vscode's integrated terminal: ``` git push origin --force-with-lease devin/edit-step-1-copy:refs/heads/devin/edit-step-1-copy; git push origin --force-with-lease devin/edit-step-2-copy:refs/heads/devin/edit-step-2-copy; ``` I wasn't paying perfect attention to the semicolon at the end of these git push lines. Some may have included a semi, some not. I think at some point, I converted a series of `git push` commands BACK into `update-ref` commands, because I did a weird rebase thing and the `update-ref` lines didn't appear on the next rebase. This is probably an error on my part, but `update-ref` lines added to `git-rebase-todo` should fail if they end with a semicolon, and the user should be forced to remove them.
