<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Thanks for the patch! Please could you add a few comments on the design of the optimised regexp, why it is faster, how it works, and so on? It really helps us to review it faster.
Also, could you please add the test cases you link to the nepomuk tests directory? If you like, submit a separate patch adding them, as a test for regexp speed and correctness would be useful in itself.
