Hello,

But you got a wrong hash I presume, because submodule weren’t actually
checked out, right?

The problem is that it papers over an actual libgit2 bug.

I think we should instead report it upstream.  Do you feel like doing
it?  I guess we’d need to give them the C version of the three-line
snippet I gave earlier.

WDYT?

Thanks,
Ludo’.
