  hgupdater receives both the pusher and author usernames,
and it uses the pusher's to create the log in JBS.

looks to me like the username of the pusher is determined by the hook
(from the ssh user name I suspect. I didn't check the details)
and sent to hgupdater along with the changeset's author,
but mercurial itself does not seem to care about the pusher's username,
so it's not persisted in the repo.
In General -pv shows a lot more info about a changeset, but the pusher
is not included, so I don't think is persisted

I suspect the use of the pusher by hgupdater was deliberate,
in order to keep track of the actual pusher,
otherwise it wouldn't be recorded anywhere
