-# The setup for all of them, pictorially, is:

-#      A
-#      o
-#     / \
-#  O o   ?
-#     \ /
-#      o
-#      B
-#
-# 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.)

-# SECTION 3: Cases involving directory renames
-#
-# NOTE:
-#   Directory renames only apply when one side renames a directory, and the
-#   other side adds or renames a path into that directory.  Applying the
-#   directory rename to that new path creates a new pathname that didn't
-#   exist on either side of history.  Thus, it is impossible for the
-#   merge contents to already be at the right path, so all of these checks
-#   exist just to make sure that updates are not skipped.
