# least by Google's internal server), but that support is pretty | ||||
# fragile and has a lot of problems on real-world repositories that | ||||
# have complex graph topologies. This could probably be corrected, but | ||||
# absent someone needing the full support for ellipsis nodes in | ||||
# repositories with merges, it's unlikely this work will get done. As | ||||
# of this writining in late 2017, all repositories large enough for | ||||
# ellipsis nodes to be a hard requirement also enforce strictly linear | ||||
# history for other scaling reasons. | ||||
