exec_command

Implements exec_command function that is (almost) equivalent to
commands.getstatusoutput function but on NT, DOS systems the
returned status is actually correct (though, the returned status
values may be different by a factor). In addition, exec_command
takes keyword arguments for (re-)defining environment variables.

Provides functions:

  exec_command  --- execute command in a specified directory and
                    in the modified environment.
  find_executable --- locate a command using info from environment
                    variable PATH. Equivalent to posix `which`
                    command.

Known bugs:

* Tests, that send messages to stderr, fail when executed from MSYS prompt
  because the messages are lost at some point.

    Forward bytes from a subprocess call to the console, without attempting to

    The assumption is that the subprocess call already returned bytes in

    Return (status,output) of executed command.

    .. deprecated:: 1.17
        Use subprocess.Popen instead

    Parameters
    ----------
    command : str
        A concatenated string of executable and arguments.
    execute_in : str
        Before running command ``cd execute_in`` and after ``cd -``.
    use_shell : {bool, None}, optional
        If True, execute ``sh -c command``. Default None (True)
    use_tee : {bool, None}, optional
        If True use tee. Default None (True)


    Returns
    -------
    res : str
        Both stdout and stderr messages.

    Notes
    -----
    On NT, DOS systems the returned status is correct for external commands.
    Wild cards will not work for non-posix systems or when use_shell=0.
