Actually this doesn't work for bzr that has a bug that adds
an extra line at the end.  So I pushed a better fix.

There are many variants what would be better to do here.
Maybe also to show all failing hunks.  And leaving point
at the beginning also makes sense, because then the user
could start applying hunks one by one with 'C-c C-a'
from the beginning until encountering the failing hunk
and handle it manually.

Agreed, the key binding is the best among bad variants.
