Bug#748688: lintian: False positive for missing-build-dependency-for-dh_-command dh_apache2 => apache2-dev if B-D is on dh-apache2

[Axel Beckert <abe@debian.org>]

Package: lintian
Version: 2.5.22.1
Severity: normal

Hi,

the dh_apache2 man page states:

    Packages making use of dh_apache2 should declare a build-
    dependency against the virtual dh-apache2 package.

But Lintian claims:

E: xymon source: missing-build-dependency-for-dh_-command dh_apache2 => apache2-dev
N:
N:    The source package appears to be using a dh_ command but doesn't build
N:    depend on the package that actually provides it. If it uses it, it must
N:    build depend on it.
N:
N:    Severity: important, Certainty: possible
N:
N:    Check: debhelper, Type: source

It seems that Lintian doesn't check the virtual package names provided
by the package it wants to see in the Build-Depends for being in the
Build-Depends. (apache2-dev provides dh-apache2.)
