I believe that will double (or more) your "changed line" count. I think
in concept something like

diff --side-by-side --suppress-common-lines <foo> <bar> | wc -l

would get a more accurate changed line count. The trick is getting this
to work with "svn diff". The best I could come up with in short order
is:

svn diff --diff-cmd mydiff | egrep -v '^Index:|=+$' | wc -l

where mydiff is the following two-line script:

shift 1
diff --side-by-side --suppress-common-lines "$@"

(The "shift 1" gets rid of the "-u" argument, which conflicts with
--side-by-side.)
