Did you run the big for loop in git.git to create the branches and then the `git pull` in git-gui?

In particular, merge_commit=$(git rev-list $c..master --ancestry-path --merges | tail -n1) is super hacky and makes a lot of assumptions.

I'm assuming you're referring to the commit that merges js/msgfmt-on-windows in: commit 90dbf226ba3fae0d932ae4e42d8d3122a47766bc Merge: 5800c63717 492595cfc7 Author: Junio C Hamano <gitster@xxxxxxxxx> Date: Jul 25 2017 Merge branch 'js/msgfmt-on-windows' of ../git-gui into js/git-gui-msgfmt-on-windows * 'js/msgfmt-on-windows' of ../git-gui: git-gui (MinGW): make use of MSys2's msgfmt git gui: allow for a long recentrepo list git gui: de-dup selected repo from recentrepo history git gui: cope with duplicates in _get_recentrepo git-gui: remove duplicate entries from .gitconfig's gui.recentrepo Since js/msgfmt-on-windows is based on 5ab7227 (Merge remote-tracking branch 'philoakley/dup-gui', 2017-03-18), when it was merged into git.git's master, the merge brought in those other four commits by Philip Oakley since they weren't merged into git.git yet. However, you're not going to be merging in the same list of commits if you merge into git-gui. You'll only end up merging in one commit: the missing 492595cfc7 (git-gui (MinGW): make use of MSys2's msgfmt, 2017-07-25). This is because Philip's commits are already in the git-gui repo. > > > > > Hope any of this is useful to anyone, > > It is very useful.
