histedit: extract a simpler function to process replacement on abort
The process replacement is building a full mapping to allow moving bookmarks and
creating obsolescence marker. We do not need the full logic for abort so we
extract it. It will be useful as abort is missing some data about the
replacement and can crash when third party extensions push it a bit too far.
