Diff has trouble with this article

[GoogleCodeExporter]

On the diff demo I tried comparing edits in an article and it's highlighting 
most of the text, instead of the minor changes.

• Merged into: Line-by-line mode sub-optimal. #38

Interesting.  I have not seen this issue before.  Even with the timeout set to 
0 and cleanup switched off, the diff is a no-op.  Will check this out...

Thank you.

• Added labels: Priority-High
• Removed labels: Priority-Medium

Confirmed.  This affects all versions.  Technically there's no bug, but this is 
clearly not expected behaviour.  As a simple workaround, turn off the line-mode 
speedup by passing False as the third argument to diff_main.

Working on finding a good solution...

This is identical to Issue 38.  Let's see if we can solve this once and for all.
