Avoid unwanted behavior change in shlex.quote (see #9723).
I simplified the quote code to use a regex instead of a loop+test when I moved pipes.quote to shlex in 5966eeb0457d; Ezio Melotti pointed out that my regex contained redundant parts (now removed) and allowed non-ASCII characters (now disallowed). I think common UNIX shells don’t quote non-ASCII characters, but there’s no harm in doing so. We’ll see if users request a change.
