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

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