Nobody outside graph.[ch] seems to have any reference to it. That might mean that it may be easier than we thought earlier to change the second parameter of this to "struct graph_line *", instead of us wrapping an incoming strbuf (which external callers are aware of, as opposed to graph_line which we prefer not to expose to outsiders). Whether we change the second parameter or not, the first clean-up may be to turn this function into a file-scope static, perhaps? All the changes are very pleasing to see. Thanks.
