Bug#924082: lintian: missing-build-dependency triggered for dh-sequence

[Jeremy Bicha <jbicha@debian.org>]

Source: lintian
Version: 2.10.0

debhelper 12 supports a new special dh-sequence- build-depends feature
[1]. For instance, a Build-Depends on dh-sequence-gnome (a virtual
package provided by gnome-pkg-tools) will automatically pass the
'--with gnome' option to dh without needing that to be specified in
debian/rules.

The lintian tags need to be updated for this. For instance, here's the
lintian errors I got with totem 3.32.0-1 targeted at experimental. The
final error "missing-build-dependency gnome-pkg-tools" triggered an
auto-reject.


E: totem source: missing-build-dependency-for-dh_-command dh_python3
=> dh-python
E: totem source: missing-build-dependency-for-dh_-command
dh_girepository => gobject-introspection
E: totem source: missing-build-dependency gnome-pkg-tools


So if you find the dh_python3 helper is being used, a Build-Depends on
dh-sequence-python3 should satisfy the requirement.

If you can, I'm requesting that this issue be fixed for Buster since a
growing number of packages will be using dh-sequence.
