Include a quick summary of the size of a change in email

Including tabular formatted text in an email can be ugly, many
user agents just use a proportional width font and assume that is
sufficient.  So instead of using a table to display the damage to
each file, just display a summary at the bottom of the file listing.
It will at least give a reviewer a notion of the length of time
they might need to review the change.
