Is this safe on Microsoft Windows? My understanding from 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.

was that you should use $(pwd) rather than raw `pwd` when comparing
against a path generated by Git. Is there a gap in my understanding
here?

I think you might be mis-reading the advice here. It is saying to use
the "pwd" program, rather than relying on the shell's $PWD variable. So
$(pwd) and `pwd` are the same thing (and are what I'm using). The $() I
think is just indicating that you'd do:

  foo=$(pwd)

And yes, I think this is a case where using the right one is important
(which is why I used the pwd program, and not $pwd in the test).

Or am I missing something else?

I was thinking, in particular, about this snippet from t/test-lib.sh:

    # git sees Windows-style pwd
    pwd () {
        builtin pwd -W
    }

If that's inherited by the subshell used in the test, then I suppose
all is okay, though I think it would not be inherited.
