t6042: Add failing testcase for rename/modify/add-source conflict
If there is a cleanly resolvable rename/modify conflict AND there is a new
file introduced on the renamed side of the merge whose name happens to
match that of the source of the rename (but is otherwise unrelated to the
rename), then git fails to cleanly resolve the merge despite the fact that
the new file should not cause any problems.
