    Revert "Cygwin: pty: Fix 'Bad address' error when running 'cmd.exe /c dir'"
    
    This reverts commit 7589034cc3151bfac8cc3d3af5e91402a78e160b.
    
    The previous commit 14816de9af69 ("Cygwin: spawn: drop special handling
    for cmd.exe and command.com") make this patch unnecessary.  The filename
    argument (i. e., run_path in the caller) is now always non-NULL.
