Run the following command over the source:
perl -pi.bak -e 's/(20[01][0-9])-2016/$1-2017/g' `git ls-files`
(Thanks Rich for the perl snippet, as used in past years.)
Reindent Python scripts to make sure lines are not longer than 80
columns.
Regarding autogenerated code (guestfs.py and bindtests.py): add an
helper function to make sure comma-separated lists are wrapped at the
wanted length.
This produces only differences in the indentation of long Python lines,
with no behaviour changes.
