Title: Fixes #202 - redict stderr in a way that doesn't break on versions of bash <4.0

The syntax `|&` for redirecting both stdout and stderr into a pipe was only introduced in Bash 4.0.

Older versions are still in widespread use; for instance, even the latest versions of OS X only ship with Bash 3.2
