Great!  I understood what what you changed meant.  Thanks.
The original one only matches the last part of a url like:

http://.../abc.def(ghi)jklmno

But yours matches:

http://.../abc.def(ghi)jkl.mno

Maybe making it match the one like

http://.../abc.def(ghi)jkl.mno/pqr(stu)vwx

is not necessary.  I've installed your patch.
