Title: Improved the graph_suite function for tests.

Graph comparision tests were failing on my Fedora 19 VM, because graphviz there uses "black" instead of "lightgrey" as one of the default colours. This change strips the problem item of the end of the line, in ```test_header:graph_suite()``` and in existing ".plain" reference files.

@benfitzpatrick - please review.
