Description:
Previously, trying to use the graph subcommand without graphviz being
installed resulted in a cryptic error message:
.
Can't exec "tred": No such file or directory at /usr/lib/perl/5.14/IO/File.pm
line 66, <STDIN> line 1.
.
graphviz is already in the Suggests field of the debian package, and
we cannot raise this dependency severity given the central role of
quilt in the debian infrastructure. This informative error message is
much more sensible.
