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
decode them.
The assumption is that the subprocess call already returned bytes in
a suitable encoding.

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.
