From 6b6112842030309c297a521918d1a2e982426fa3 Mon Sep 17 00:00:00 2001

Subject: [PATCH 02/11] Document PART-POLICY lines
PART-POLICY has been accepted in mdadm.conf since the same
time that POLICY was accepted, but it was never documented.
So add the missing documentation.
Also fix a bug which would have stopped it from working if
anyone had ever tried to use it.
