I'll take Peff's hint, tweak/add comments for correctness and symmetry
with the previous patch and add an if-BUG for symmetry.

Here's a reroll of ma/split-symref-update-fix. The first three patches
are v3 plus Michael's Reviewed-By.

The fourth is the conceptual fix of adding `refname` instead of "HEAD"
into the list of affected refnames.

Thanks all for comments, suggestions and help along the way.

This looks good to me, including the explanation in the new patch.
Thanks!
