[issue9723] Add shlex.quote

[Éric Araujo]

Éric Araujo <merwok at netwok.org> added the comment:

I suck at regexes, but the one I came up with lets quote pass the tests that existed for pipes.quote, so I figure it’s good.  I did not change the string operations at the end of the function (+ and replace) as it was simple and working.

In the absence of review or opposition here, I have committed my patch.  Feedback welcome.
