(Programmer hat) Why build system need to know, which distro it is build
on? I guess (did not check sources) you actually interested in
something more specific, then name of distribution (my
linux-from-scratch installation does not have name, for example).
Yes, name of distribution (although now for current Debians there is one target 'debian', but e.g. for ubuntu we have special target for trusty to use upstart instead of systemd).
Added a debian/watch, not sure why mentor lintian doesn't see it, uscan doesn't report any error, it should get our official tar.gz release for github.
Fixed the overrides and indentation.
