Summary:
I, as an author, sometimes forget branch associated with a revision.
Plus setting ##differential.show-host-field## makes a false sense of security
that branch will stay hidden so that I can name it
//finally_solve_this_crap_which_makes_no_sense//. But it is published in
Accepted and Request Changes e-mails anyway.
Test Plan: Display revision with disabled ##differential.show-host-field##.
