Bug#614879: [checks/rules] false positive missing-build-dependency-for-dh_-command for dh_python{2,3}

[Jakub Wilk <jwilk@debian.org>]

Package: lintian
Version: 2.5.0~rc1

Some packages using dh_python2/dh_python3 trigger false-positive lintian 
errors:

$ grep ^Build-Depends mako_0.4.0-1.dsc
Build-Depends: debhelper (>= 5.0.38)
Build-Depends-Indep: python-all, python-setuptools, python3-all, python3-setuptools, python-sphinx, python-nose, python-markupsafe

$ lintian mako_0.4.0-1.dsc
E: mako source: missing-build-dependency-for-dh_-command dh_python2=python
E: mako source: missing-build-dependency-for-dh_-command dh_python3=python3


For a package using dh_python2, it should be enough to 
build-depend(-indep) on one of: python, python-all, python-dev, 
python-all-dev.

For a package using dh_python3, it should be enough to 
build-depend(-indep) on one of: python3, python3-all, python3-dev, 
python3-all-dev.
