[PATCH] mingw: fix the shortlog --output=<file> test

[Johannes Schindelin <Johannes.Schindelin@gmx.de>]

Adjust t4201 to pass on Windows; a couple of test cases need to be
skipped on Windows which leads to a different shortlog than on Linux.

Let's just fix that by limiting the shortlog's commit range to traverse
only one commit: that guarantees that it does not matter how many test
cases were skipped.

	Dang it! My original test series was well-tested on Linux *and* on
	Windows. Over the course of the iterations, Windows support broke.

	My apologies for not catching this earlier.
