vimdiff has an annoying habit of displaying two almost-completely-different lines as the same partially-different line just because they share a character in common at the beginning or end.
The quick brown fox jumps over the lazy dog.
This is a completely different line.
vimdiff foo.txt bar.txt displays these two lines side-by-side with everything but the
Th at the beginning highlighted.
Is there a way to disable this behaviour and just display different lines as being different lines?
