ElyTree: no Git version in the status bar; plain real paths on Windows

The component pin moves to bd01470 (long change-list names end before the
row's buttons). Real paths come from dunce, so Windows shows C:\... rather
than \?\C:\..., and 36 more ElyTree tests pass there. The lock returns to
windows-sys 0.61, which the last pin change had resolved down.
