viric's flavour of fossil, which includes the cherry-picked changes out of trunk: [d0b1b1114] [39e165afb] [dad37196f] [f309130a8]. This outdates the branch annotate_links ([f14798e0e3]), which has some extra changes, some hard to port.

This lets the browser pick the right program to open them straight. check-in: b31afcc2 user: viriketo tags: viric_flavour
