hgview #86271 Hide non-interesting changesets [open]

From Hans Meine's email on Hg ML:

Ideally, I would say that all these [non-intersresting] changesets should not be displayed at all (cf. the "Hide Merges" toggle in TortoiseHg); instead

  • the tags are displayed anyway
  • closed branch heads could get a special (dead-end) icon
  • merges should be hidden, but the graph should join between the surrounding changesets
