[PATCH 1/2] t4034-diff-words: replace regex for diff driver

[Tay Ray Chuan <rctay89@gmail.com>]

The next patch uses a non-whitespace regex, similar to the regex
currently used by the 'testdriver' diff driver; replace the regex with a
distinct one so that we can continue to conclude its effects.

Kept separate to keep the next patch clean.
