That would mean that the width of the text could vary, which would
require a bit more work to handle.

In some places, the nesting goes deep, and it would be hard to show all
of the levels.  Pull, for example, has two phases: fetch and merge.
fetch has several phases, and progress is displayed within each fetch
phase.  Merge is also divided into phases, which are subdivided by file.

Perhaps just the top and bottom level?

|   [==============] phase (1/3) / fetching files

I certainly don't have a problem with adding more detail to the progress
bars.  I left them sparse because I didn't have a better idea what to do
with them.
