    patch 8.2.4060: win_execute() slow on systems where getcwd()/chdir() is slow

    Problem:    win_execute() is slow on systems where getcwd() or chdir() is
                slow. (Rick Howe)
    Solution:   Avoid using getcwd() and chdir() if no local directory is used and
                'acd' is not set. (closes #9504)
