For the migration script, I need a (less hacky) way of programmatically modifying a status file. As a step along that path, I need the ability to write a status file to disc given a StatusFile object. With that, it was a small step to write a little "formatter" that turns a status file into its canonical representation. It removes unneeded parentheses in expressions, normalizes expectation case, and normalizes whitespace. Seems useful. R=whesse@google.com Review-Url: https://codereview.chromium.org/2988383002 .
