Sorry, I cannot do that. If I would know where (and how) to fix it I would
already do that. You must understand that although now this serves as an
exercise for GSoC, it is a real issue which is in GRASS. Also, for the GSoC
you will need to understand the existing code to certain extended to be
able to incorporate your code and to fix the bugs which can emerge in both
new and existing code.
