Subject: [PATCH] graph: output padding for merge subsequent parents
When showing merges in git-log, the same commit is shown once for each
parent. Combined with "--graph" this results in graph_show_commit()
being called once for each parent without graph_update() being called.
Currently graph_show_commit() does not print anything on subsequent
invocations for the same commit (this was changed by commit 656197a -
"graph.c: infinite loop in git whatchanged --graph -m" from the previous
behaviour of looping infinitely).
Change this so that if the graph code believes it has already shown the
commit it prints a single padding line.
