# criss-cross with regular files that have conflicting modes:
#
# B D
# o---o
# / \ / \
# A o X ? F
# \ / \ /
# o---o
# C E
#
# Commit A: nothing of note
# Commit B: introduce file source_me.bash, not executable
# Commit C: introduce file source_me.bash, executable
# Commit D: merge B&C, resolving in favor of B
# Commit E: merge B&C, resolving in favor of C
#
# This is an obvious add/add mode conflict. Can git detect it?
