Hm, indeed, the author field should have been Greg Hogan; not sure what
happened there (I applied it with 'git am -3' as usual); hence my
sign-off in the commit message metadata.  I'll pay more attention to
these in the future.

Greg had marked it for the staging branch, but my summary verification
led me to believe only 347 packages would be impacted for (which I remember
finding a bit surprising):

--8<---------------cut here---------------start------------->8---
$ guix refresh --list-dependent git
Building the following 186 packages would ensure 347 dependent packages
are rebuilt: debops@1.1.0 git-repo@2.4.1 simavr@1.7 libjcat@0.1.9 [...]
--8<---------------cut here---------------end--------------->8---


--8<---------------cut here---------------start------------->8---
$ guix refresh --list-dependent git-minimal Building the following 69
packages would ensure 213 dependent packages are rebuilt:
pplacer@1.1.alpha19 bap@2.0.0 [...]
--8<---------------cut here---------------end--------------->8---

But I missed the git-minimal/fixed variant.  I should have tried the
'guix build libreoffice' test!

Yeah, I don't think it's worth it.  Reverted it for now, and applied the
original version that didn't touch the trailing #t:

--8<---------------cut here---------------start------------->8---
78e8c20179 origin/master gnu: git: Update to 2.35.1.
8a9bf794e1 Revert "gnu: git: Update to 2.35.1."
--8<---------------cut here---------------end--------------->8---

Thanks for the report, and sorry for the mess :-)
