Related to https://gitlab.com/gitlab-org/gitlab-ee/issues/212 When using `--autorebase` `squash!` commits behave differently to `fixup!` commits because a squash combines two commits changes including commit message, and should allow the person squashing the commits to review and modify the commit message. We should support both in a manner consistent with Git. ### Proposal If a commit contains `squash!` commits, the user should be shown a prompt to review the commit messages of the commits that will be squashed and be able edit them. Example: ``` # This is a combination of 3 commits. # The first commit's message is: changed my name a bit # This is the 2nd commit message: updated README formatting and added blame # This is the 3rd commit message: added cat-file ``` ### Links / references - https://git-scm.com/docs/git-rebase#git-rebase---autosquash - https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History
