Re: [PATCHv4 3/4] t5520-pull: --rebase with rebased upstream and two branches

I think marking breakages here is a good thing to do, but I do not think
this belongs to your rest of the series.  If a fix for this will upcoming
(I think I've outlined ideas in a separate message, IIRC), I think that
could go to 'maint', to which the remainder of your series will definitely
not belong to.

I'd queue this one separately from the other three patches (which will
fork from 'master'), which means this should not depend on [2/4], but
unfortunately it does.
