Merge remote-tracking branch 'mcv/debian/1.1'

This incorporates debian/changelog fixes from Debian itself.
They don't (necessarily!) reflect changes to master, for
instance Debian bug #766455 is fixed in a different way.

# Please enter a commit message to explain why this merge is necessary,
# especially if it merges an updated upstream into a topic branch.
#
# Lines starting with '#' will be ignored, and an empty message aborts
# the commit.
