narrow: update the narrowspecs to new ones after pulling when widening The ellipsis case updates the new narrowspecs at bundle2 handling code, and non-ellipsis widening didn't use to work and never set the new narrowpats. Previous pacth added server side logic for widening without ellipsis. This patch adds the missing repo.setnarrowpats() so that we set the new narrowpats after widening in non-ellipsis cases also. This makes widening with non-ellipsis case work but there are certain things which we can improve. Differential Revision: https://phab.mercurial-scm.org/D4384
