Provide convinience access to the raw subject

[epage]

When writing committed, I need access both to the actual subject (without prefix) but also the raw subject (for determining line length). Rather than me having to separately parse the commit to get the raw subject, it'd be nice if the conventional parser did it for me.

If you have the commit string, doesn't "feat: description\n\nbody".lines().next() give you what you need?

I guess we could add a header() accessor, to go alongside the body() accessor.

Technically yes, "feat: description\n\nbody".lines().next().unwrap() works but nicer to have that abstracted.
