[PATCH v3 1/7] t4052: test --stat output with --graph

[Lucian Poston <lucian.poston@gmail.com>]

From: Zbigniew Jędrzejewski-Szmek <zbyszek@in.waw.pl>

Add tests which show that the width of the --prefix added by --graph
is not taken into consideration when the diff stat output width is
calculated.
