I think this is an issue of the cost of forking a filter process for
each line in the log view.  Now that we have Lua filters that may not be
so much of an issue, but I don't think we can just start using the
source filter on the log view due to the impact that will have on people
with an "exec" source-filter already configured.

Perhaps we need to add a "log-filter" which you could configure to be
the same as "source-filter" but which can be left blank for people whose
links are normally in the body of the commit message.
