Post #1836250

So I have finally a history rewtire features implemented: fixup / squash commits. But with some severe limitations: - working copy and index must be clean - no rebase / merge / cherry-pick may be in progress - all selected commits must be reachable from HEAD via first-parent walk - no commit between the oldest selected and HEAD (inclusive) may be a merge commit - the oldest selected commit must have a parent (cannot be the root commit) #gitte
