Poor advice on my part when reviewing the previous round. When I had
read in git/t/README (in the distant past):

    When a test checks for an absolute path that a git command
    generated, construct the expected value using $(pwd) rather than
    $PWD, $TEST_DIRECTORY, or $TRASH_DIRECTORY. It makes a difference
    on Windows, where the shell (MSYS bash) mangles absolute path
    names.  For details, see the commit message of 4114156ae9.

I must have missed the word "check" in the first sentence.
