I've added some examples. If you diff -u the before and after files
you should get something like the png at
Note that the bottom two block edits didn't render as block edits
because a rows was added or inserted. The script does not try to merge
lines when presented with N minus lines followed by other-than-N plus
lines. It only wants to merge N minus lines with N plus lines.
Another case you might be hitting is that if too many edits are done
in a line, it decides that it would look better to show you "this
whole line changed into this other whole line" rather than trying to
merge the two lines.
As for input, basically anything that looks like diff or diff -u. That
would include svn diff and git diff and git log -p.
