Comment (by teor):

 Notes for 9c3be06e51cacfbe472042d17120805dd0a262bf:

 {{{
 <teor> The minimal impact change is to treat "0 descriptors from 0 exits"
 as 1.0 (unlike guard and middle, where 0 from 0 is treated as 0.0).
 <nickm> I think that the case where no exits exist is weird enough that
 it's okay to treat that special, as opposed to complicating cases that
 more people will encounter
 }}}

 Also split off "don't build doomed circuits" into another commit.
