I first wondered if we would get a division-by-zero while scaling
the graph, but we do not scale smaller numbers up to fill the
columns, so we should be safe.

Note that we should be safe for a totally different - and more
fundamental - reason: the zero line case is by no means new. We've
always done it for the rename case.

These days, we omit 0 insertions and 0 deletions, so I am not sure
what you should get for this case, though:

quoted

 Makefile | 0
 1 file changed, 0 insertions(+), 0 deletions(-)

Should we just say "1 file changed"?

If that is what it does for the rename case, then yes. I think it
should fall out naturally.
