  15 # To help make it easier to follow the flow of tests, they have been
  16 # divided into sections and each test will start with a quick explanation
  17 # of what commits O, A, and B contain.

  19 # Notation:
  20 #    z/{b,c}   means  files z/b and z/c both exist
  21 #    x/d_1     means  file x/d exists with content d1.  (Purpose of the
  22 #                     underscore notation is to differentiate different
  23 #                     files that might be renamed into each other's paths.)
