These tests should really be in t0060-path-utils.sh.

These tests fail on Windows because test-path-utils operates on a
DOS-style absolute path even if a POSIX style absolute path is passed as
argument. The best thing would be to move this to a separate test that is
protected by a POSIX prerequisite (which is set in t0060).

pwd -P actually expands to pwd -W on Windows, and produces a DOS-style
path. I suggest to insert [^/]* to skip drive letter-colon like so:

	d=$(pwd -P | sed -e "s|^\([^/]*/[^/]*\)/.*|\1|") &&

Then these tests pass.
