The description of the observed problem makes sense. Thanks for
working on this.

This simplification of the comment makes sense, especially with the

This new blank line is probably unwanted.

OK. So the idea is that a successful force-with-lease push would
have a zero reject_reason at this point, and the if/else cascade
would still trigger and would set it to STATUS_REJECT_NEEDS_FORCE,
just like a usual forced push without a lease. And then because the
local variable force_ref_update is set, it would report the forced
success exactly the same way as the usual forced push.
Sounds very sensible.
Do we want to make sure that other people will not break this fix in
the future by adding a few tests, perhaps to t/t5533?
Thanks.
