[PATCH v7a 7/9] diff --stat: add a test for output with COLUMNS=40

In preparation for the introduction on the limit of the width of the graph part, a new test with COLUMNS=40 is added to check that the environment variable influences diff, show, log, but not format-patch. A new test is added because limiting the graph part makes COLUMNS=200 stop influencing diff --stat behaviour, which isn't wide enough now. The old test with COLUMNS=200 is retained to check for regressions.
