- Update our woefully out of date doc comment for WebRequest::getPathInfo (we haven't simply been extracting a PATH_INFO for ages)
- Make PathRouter::makeWeight protected
- Add more comments to the PathRouter code
- Add two more edge case tests to the PathRouter tests.
* Removed a bit of cruft in from a comment (c&p error)
* Clarified 'value' params comment (AFAIK)
* Broke some long lines and made some other w/s cleanups
