Thomas, All,

On 2016-01-27 21:32 +0100, Thomas Petazzoni spake thusly:
> Just like the --stop-on and --exclude options allow to stop on or
> exclude virtual packages from the list by passing the "virtual" magic
> value, this commit extends the graph-depends logic to support a "host"
> magic value for --stop-on and --exclude. This will allow to draw the
> graph by stopping on host packages, or by excluding host packages.

Can we make that line look like the corresponding line for the virtual
packages, two-and-three lines above?
