Currently, we have identical code for generating revision marks ('<', '>', '-') in 5 places. Factor out the code to a single function get_revision_mark() for easier maintenance and extensibility. Note that the check for !!revs in graph.c (which gets removed effectively by this patch) is superfluous.
