I'd do it just like that.

You can get the list of revisions with:

svn log -q $REPO/path/to/x \
| sed -n 's%^r%%p' \
| awk '{print $1}'

For each revision, run:

svn diff -c $REV $REPO/path/to/x

Not sure how to do this. You can start with:

svn blame $REPO/path/to/x \
| sed -n $M,$Np \
| awk '{print $1}'

This will print the most recent revisions to touch each of the lines
in the range $M to $N. However, where you go from here is unclear.
Any of those revisions, or preceding revisions, might have added or
removed lines. How do you programmatically know where your range of
lines is in the earlier revision?
