Bug#768119: lintian: false positive on weak-library-dev-dependency

[Norbert Preining <preining@logic.at>]

Package: lintian
Version: 2.5.30
Severity: normal

I have
	E: gwaei source: weak-library-dev-dependency libwaei-dev on libwaei2 ((>= ${source:Upstream-Version}), libwaei2 (<< ${source:Upstream-Version}+1~)

which is exactely what lintian suggests:

 Sometimes, such as for -dev packages that are architecture-independent to
 not break binNMUs or when one doesn't want to force a tight dependency, a
 weaker dependency is warranted.  Something like <tt>(&gt;=
 ${source:Upstream-Version}), (&lt;&lt;
 ${source:Upstream-Version}+1~)</tt>, possibly using
 <tt>${source:Version}</tt> instead, is the right approach.  a....

Thanks
