Subject: [PATCH] Direct output from fail() to stderr
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This allows callers to more easily differentiate valid output from
errors.  A recent example is facter.  When calling virt-what for its
virtual fact, it gets 'virt-what: this script must be run as root' as
the fact value when run as non-root:

$ facter | grep ^virtual
virtual => virt-what: this script must be run as root

This is mildly related to RHBZ #719611¹.
