A patch to make sure an exception'ed cluster wouldn't cause hit page
display to suffocate. Will commit soon if no objection.
Dawid: clusterHits() throws exception
"Unidentified problems with the clustering.",
if docs contain long line of hyphens (or just long line of any character?).
I have one setup with many excel files. Their parsed texts (using xlhtml)
are ascii formated using dashes as rectangular boxes.
It will be nice if clusterHits() can handle them gracefully.
Of couse, I can add one more filter to strip them off. But that's ugly.
