Comment 7 for bug 376073

This fix should be high priority.

It can be hard to prove a negative.
The same goes for documents.
I.e. Professional people who use .pdf readers sometimes have a need to prove something does not exist in a document.
They can do this by searching for the thing they need to disprove.

But if the search does not work properly because it can't spot strings that fall over lines, and they don't know that this fault exists, they will end up making decisions based on faulty information given them by the software.
