# rev-limit =3
#
# 1-a -- 2-b
# \-- 2-c -- 3-d -- 4-e
#
# 4-e wrtten twice:
# 1) with one ancestor only (e - d)
# 2) with a full history
#
# Second write extends the fist tree and leaves the earlier fragment behind
as a
# duplicate and stem repairs it. Before we used to cut each leat to
revs_limit
# on its own (dropping 1-a from the long branch even though 1-a stays in the
# path as the parent of 2-b).
#
# TL;DR:
# before the fix {"start":4,"ids":["e","d","c"]}
#
# with the fix {"start":4,"ids":["e","d","c","a"]}
