dotdepends-merge on DETAIL.dot files: wrong red border

[Kyle Nitzsche]

dotdepends 0.3.15:

One can merge two generated pkg-DETAIL.dot files to produce a graph showing both trees.

Red-borderd nodes are supposed to indicate pkgs that would ONLY be installed if Install-Recommends is true.

Black-bordered nodes indicate pkgs that would be installed by a direct dependency (regardless of Install-Recommends setting).

However, the attached png shows libdb5.1 as red-borded. It should be black-bordered since it would be installed if either vim or fontconfig were installed through direct depends, regardless of Install-Recomends setting.
