  I had originally pushed for this to be templating or at least additional configuration for the graphlog, we currently have ways of changing the | and : markers via config (not template), but these don't support unicode because of https://www.mercurial-scm.org/repo/hg/file/tip/mercurial/graphmod.py#l476, which is for this: https://www.mercurial-scm.org/repo/hg/file/tip/tests/test-glog.t#l3072
