I think leaving the u in the comment is better, but I can see it should be unnecessary.

What would actually be better is a description of what doer is compared to u. I'm struggling to think of something succinct & pithy though.

Perhaps: CreateRepository creates a repository as doer for the provided user/organization u

@lafriks I think this should be a bug rather than an enhancement.
