Thanks for the submission. Minor comments below to give you a taste of what it's like to contribute to this project... On Sat, Mar 1, 2014 at 5:42 PM, kgeorgiou [off-list ref] wrote:

Space after colon. You might be able to provide more information in
the short summary of the subject. Perhaps something like this:
Subject: skip_prefix(): avoid scanning 'prefix' twice
Rewritten git-compat-util.h:skip_prefix() as a loop, so that it doesn't have to scan through the prefix string twice as a miniproject for GSoC 2014.
Good description. In this project, use imperative tone:
Rewrite skip_prefix() as loop...
(I've just noticed that this miniproject has already been tackled by another contributor, if that's a problem I can pick something else.)
That's okay. The purpose of the miniprojects is for you to get a taste of what it's like to contribute to this project and to understand what will be expected of you as a GSoC student; and to give the GSoC mentors a chance to judge your abilities and observe how you interact with reviewers.
Looking forward to any kind of feedback. - Kyriakos Georgiou
There are two types of information you want to convey to readers. (1) Patch description, explanation, justification before the "---" line which is recorded in the permanent project history. (2) Commentary below the "---" line for readers of the patch but not of interest once the patch is accepted officially. The "as a miniproject for GSoC" and all lines following it are just commentary which should go below the "---" line.
