[PATCH] checkout tests: enable test with complex relative path

[Stefan Beller <stefanbeller@googlemail.com>]

This test was put in, but commented out in fed1b5ca (2007-11-09,
git-checkout: Test for relative path use.)
It's been a while since 2007 and the intended test case works now.
(I could not find the enabling commit in ls-files however.)

The code in question however did not change into the sub directory,
so we still need to add a 'cd'. Also a test for the file content has been
added. This is already part of the other tests for checkout.
