Subject: Make graph_next_line() available in the graph.h API
X-Git-Tag: v1.7.3-rc0~77^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=6bdc17d9a69bdd736901b115841479f5782a510e;p=git.git

Make graph_next_line() available in the graph.h API

In order to successfully use the graph API from a context other than the
stdout/command-line scenario (where the graph_show_* functions are
suitable), we need direct access to graph_next_line(), to drive the
graph drawing process.
