Reword "your branch has diverged..." lines to reduce line length

The message length depends on the length of the branch name.  In my case,
the branch name "origin/add-chickens2" put the first line of the "your
branch has diverged" message over 80 characters, which triggered "less -FS"
to not exit automatically as expected.

This patch rewords the messages to make the lines generally shorter, so
that you'd need a significantly longer branch name to trigger the problem.
