  4323 Test 'graphwidth' in 'hg log' on various topologies. The key here is that the

  4324 printed graphwidths 3, 5, 7, etc. should all line up in their respective

  4325 columns. We don't care about other aspects of the graph rendering here.

  4421 The point of graphwidth is to allow wrapping that accounts for the space taken

  4422 by the graph.

  4456 Something tricky happens when there are elided nodes; the next drawn row of

  4457 edges can be more than one column wider, but the graph width only increases by

  4458 one column. The remaining columns are added in between the nodes.
