Summary: shlex.split problems on Windows
Initial Comment:
What is shlex.split supposed to do on Windows? It seems to be present but it
can't handle basic Windows pathnames : shlex.split("C:\\directory\\file")
returns C:directoryfile (whereas os.system happily accepts the same string).
Also, it runs in POSIX mode and there is no way to override it! Why isn't POSIX
mode the default on POSIX systems and not on non-POSIX systems? Or for it to at
least be possible to says shlex.split(s, posix=False)?

Further quote: "This will often be useful for writing minilanguages, (for
example, in run control files for Python applications) or for parsing
quoted strings."
Why shouldn't that feature not be available under Windows?
Again, shlex is *not supposed* to handle Windows command lines.
Also, http://docs.python.org/lib/shlex-parsing-rules.html clearly says
what the difference between
"posix=True" and "posix=False" is.
That non-posix mode works on Windows filenames is because it does not
handle backslash escapes.

Then what is "non-POSIX mode" if it's only supposed to work on UNIX?
I noted the initial comment but it seemed to be out of date. Especially as
it
seems to work fine to copy shlex.split and correct the default value for
"posix".
Seemed a very simple change that had little chance of being wrong.
If Windows behaviour is really unsupported then surely the function should
not
be available there.

The docs to shlex say: "The shlex class makes it easy to write lexical
analyzers for simple syntaxes resembling that of the Unix shell."
It is not meant to be a cross-platform shell quoting handler, but an
implementation of Unix shell behavior.
