I think that's a huge improvement.

I don't know if it's feasible with the current graphing code (I suspect
not), but it might also be nice if we could trim lines that would continue
past the end of the graph (and indicate that with an *) e.g.

  o    changeset:   32:d06dffa21a31
  |\   parent:      27:886ed638191b
  | :  parent:      31:621d83e11f67
  | :  user:        test
  | :  date:        Thu Jan 01 00:00:32 1970 +0000
  | :  summary:     (32) expand
  | :
  o :  changeset:   31:621d83e11f67
  |\:  parent:      21:d42a756af44d
  | :  parent:      30:6e11cd4b648f
  | :  user:        test
  | :  date:        Thu Jan 01 00:00:31 1970 +0000

  | :
  o :    changeset:   30:6e11cd4b648f
  |\ \   parent:      28:44ecd0b9ae99
  | ~ :  parent:      29:cd9bb2be7593
  |   :  user:        test
  |   :  date:        Thu Jan 01 00:00:30 1970 +0000
  |   :  summary:     (30) expand
  |   :

would become:

  o    changeset:   32:d06dffa21a31
  |\   parent:      27:886ed638191b
  | :  parent:      31:621d83e11f67

  | :  date:        Thu Jan 01 00:00:32 1970 +0000
  | :  summary:     (32) expand
  | :
  o :  changeset:   31:621d83e11f67

  | :  parent:      30:6e11cd4b648f
  | :  user:        test
  | :  date:        Thu Jan 01 00:00:31 1970 +0000
  | :  summary:     (31) expand
  | *
  o    changeset:   30:6e11cd4b648f
  |\   parent:      28:44ecd0b9ae99
  | ~  parent:      29:cd9bb2be7593
  |    user:        test
  |    date:        Thu Jan 01 00:00:30 1970 +0000
  |    summary:     (30) expand
  *
