Bug#881047: libapt-pkg5.0: for apt_preferences, glob and regexp are buggy on the colon character ":"
Control: retitle -1 apt: the apt_preferences(5) man page is not multiarch aware
Control: reassign -1 apt
Control: found -1 1.6~alpha4
Control: found -1 1.6~alpha6
Reassigning to apt since this is where the apt_preferences(5) man page
is.

There are 2 things to fix in the apt_preferences(5) man page, and
perhaps in some other places:
1. The description for multiarch. Currently, there is nothing about
multiarch.
2. The examples: the "Package: *" lines are incorrect if the goal
is to match all packages (for multiarch machines).
