Thanks Johannes for generously reviewing my patch. It indeed is going to improve the thing a lot. I agree with all your comments so far, and will submit a newer patch soon. Since this is my first patch, I have couple of questions regarding submitting the patch: 1. Is there a page/place where I can see the review comments rather neatly ?, finding out all the comments and infact reading to entire code on text file is cumbersome. If there is no way, then its fine,... I can live with it. 2. When I address the review comments and want to resubmit the patch, do I need to submit the incremental patch or the entire code patch again ? git-format-patch gives me incremental patch only.
