pull: pass rev to check out as integer to postincoming() I don't know if there's ever been a need for it to be a string (it's been like that since 02f40b2ece3f (commands: use rev from remote repo when updating as part of a pull, 2009-10-21)). I'm soon going to require it to be an integer, so let's fix this first. Differential Revision: https://phab.mercurial-scm.org/D3086
