Yeah, we could go there right now (using perhaps "--pretty" or
"--format" instead of "--style", so that we are more consistent with
other commands), but on the other hand we don't know yet if the other
formats will really be needed.

Yeah, that's another possibility for the future. People might want a
--json option that can be used both with and without --oneline. But as
the future is difficult to predict, let's try to make it easy for us
in both cases.
And I think starting with just "--oneline" would be easier to deal
with later than "--normalize" (or "--style" or "--pretty" or
"--format") especially in the latter case.
