Well who knows what people might want/need?
Anyway in `git log` --oneline is not a direct mapping with
--pretty=oneline as it also means --abbrev-commit, and this is not a
big problem.

Yeah, we could call that --no-fold or --no-wrap if we expect to need
--fold=72 or --wrap=72.
At least it is more descriptive than --normalize and if we later
introduce --pretty or --format we can say that it is a shorthand for
--pretty=nofold or --pretty=unfolded.

Though "fixing" this after a release has been made might introduce a
regression for people who would already use the option on trailers
with different separators. That's also why I don't like --normalize.
We just don't know if we will need to "fix" it a lot to make sure
scripts using it will work in all cases.

If we use --no-fold or --oneline instead, we don't promise too much
from this option, so users cannot say that they expect it to work for
them in all cases.
