git-maintainance-scripts: merge-forward should provide indications of merges actually occuring
I'd like the merge-forward script (see legacy/trac#29391 (moved)) to highlight me the merge-forwards that actually merged something, contrary to the ones that were NOPs.
My fear is that I will have left some garbage in my worktrees and a merge-forward will merge forward something that I have not anticipated (e.g. from 035 to 040, when I just wanted to merge-fwd from 040 to master).
This has not yet happened, but I'd like as much protection as possible when using these automatic tools :)
