I don't know the technical details of why this change is needed.
But someone felt it was important enough to put in t/README.

  - 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.
