[PATCH 0/2] Fix git subtree on Windows

In the topic branch ls/subtree, we saw a lot of improvements of the git subtree command, and some cleaning up, too. For example, 22d550749361 (subtree: don't fuss with PATH, 2021-04-27) carefully laid out a history of changes intended to work around issues where the git-subtree script was not in the intended location, and removed a statement modifying PATH in favor of a conditional warning (contingent on the PATH being in an unexpected shape).

This particular condition, however, was never tested on Windows, and it broke git subtree in Git for Windows v2.32.0, as reported here [https://github.com/git-for-windows/git/issues/3260]. Now, every invocation of git subtree, with or without command-line arguments, results in output like this:

It looks like either your git installation or your git-subtree installation is broken.

Tips:
 - If `git --exec-path` does not print the correct path to
   your git install directory, then set the GIT_EXEC_PATH
   environment variable to the correct directory.
 - Make sure that your `git-core\git-subtree` file is either in your
   PATH or in your git exec path (`C:/Users/harry/Downloads/PortableGit/mingw64/libexec/git-core`).
 - You should run git-subtree as `git core\git-subtree`,
   not as `git-core\git-subtree`.

This patch series provides a band-aid to that symptom, and is based on ls/subtree.

  subtree: fix the GIT_EXEC_PATH sanity check to work on Windows
  subtree: fix assumption about the directory separator
