[python-committers] Use hg commit --user?

Hi,

I do sometimes commit patches written by someone else. I tried to always add him/her to Misc/ACKS and in the changelog entry (Misc/NEWS). With git, it's possible to record an author different than the commiter. In Mercurial, I see a --user option.

Can I use this option to commit a patch written by someone else? Or is there another option for that?

If I use hg commit --user, is it possible to see somewhere that the commiter was me?
