> As I can see, you use master(4.99), not 4.8.0, right?
I use neither branch master, nor tag v.4.8.0.
I reproduced this using a specific commit
(241553f21ce38eae821ea4c1e12241365563d444) that to me appears to be
the one that introduces the problem.
This commit is included in (ancestor of) screen-v4, v.4.8.0 and
v.4.9.0 but not in master.

$ isancestorof() { if git merge-base --is-ancestor $1 $2; then echo $1
is included in $2; else echo $1 is NOT included in $2; fi; }
$ for rev in origin/master v.4.8.0 v.4.9.0 origin/screen-v4; do echo
$rev is $(git rev-parse $rev); isancestorof
241553f21ce38eae821ea4c1e12241365563d444 $rev; done
