Code Issues Proposed changes

include unchanged files in series_diff_start.sh

Browse Source 
It's hard to compute how many files changed, because with renames and
deletions it can look like more changed than exist now. It's easier to
compute how many files *did not* change, by looking at which SHAs are
referenced from the git trees at the start and end point.
