 Set up the config with two simple fixers: one that fixes specific line ranges,
 and one that always fixes the whole file. They both "fix" files by converting
 letters to uppercase. They use different file extensions, so each test case can

 Tests for the fix extension's behavior around non-trivial history topologies.
 Looks for correct incremental fixing and reproduction of parent/child
 relationships. We indicate fixed file content by uppercasing it.
