viewdiff: diff_before_or_after: avoid extra capture

/(.*?)\z/ will capture the "$X insertions(+), $Y deletions(-)"
bit anyways, along with whatever extra notes before the
/^diff --git / line.  So just rely on /(.*?)\z/ and avoid
the special case before it.

1 files changed, 4 insertions, 4 deletions
