Merge ~nacc/git-ubuntu:lp1735744-fix-lint-arguments into git-ubuntu:master

[Nish Aravamudan]

Make jenkins happy.

[Christian Ehrhardt  (paelzer)]

Code change is small and looks reasonable.

Tested from the branch and now I can successfully add e.g. --target-branch=pkg/debian/sid and it works to check it.
