I figured it out. It does not happen with your `ab/no-kwset` patch series
in isolation, it's only when it is merged into `pu`, and the culprit is
the bad interaction with the `js/mingw-use-utf8` branch.

To fix it, I have a tentative patch:
https://github.com/git-for-windows/git/commit/e561446d

So I'll head over to that patch series and add more information there.

Ciao,
Dscho
