SF bug 418615: regular expression bug in pipes.py.
Obviously bad regexps, spotted by Jeffery Collins.
HELP! I can't run this on Windows, and the module test() function
probably doesn't work on anyone's box. Could a Unixoid please write
an at least minimal working test and add it to the std test suite?
