[Dctrl-tools-devel] Bug#595582: dctrl-tools: grep-aptavail complains: "Ignoring file 'apt-build' in directory '/etc/apt/sources.list.d/' as it has no filename extension"

[Julian Gilbey]

Package: dctrl-tools
Version: 2.14

polya:~ $ grep-aptavail -P foobar
N: Ignoring file 'apt-build' in directory '/etc/apt/sources.list.d/' as it has no filename extension

I'm not sure whether this is a bug in grep-aptavail or in apt-build.
