Three examples below.  I believe the second is wrong, because it reorders
the "echo" and "," tokens.

>>> list(shlex.shlex('echo b="a",echo bar', posix=True))
['echo', 'b', '=', 'a', ',', 'echo', 'bar']
>>> list(shlex.shlex('echo b="",echo bar', posix=True))
['echo', 'b', '=', 'echo', ',', 'bar']
>>> list(shlex.shlex('echo b="",echo bar'))
['echo', 'b', '=', '""', ',', 'echo', 'bar']

This is also broken in 3.5.2, but not in 3.6.0:

>>> list(shlex.shlex('echo b="",echo bar', posix=True))
['echo', 'b', '=', '', ',', 'echo', 'bar']

I'm guessing it was fixed incidentally by the changes in issue1521950.

My mistake, it was addressed directly in issue21999. This is already fixed in 2.7.13 and will be fixed in 3.5.3.
