Bug Description

On the latest bzr.dev code I changed NEWS by adding "hello" to the end:

echo hello >> NEWS

Then I ran:

bzr qdiff --complete NEWS

and my CPU went to 100%. After about 20 seconds the window appeared which is a really long time seeing as only one line has been added to the file...

Lukas said qdiff should be rewritting in C++ for speed. I'm newbie in PyQt and have no experience in C++Qt, so the best we can do for 1.0 is to disable this option to reduce user complains. Sorry.
