Use imperative tone: "rewrite" instead of "rewrote". The subject is a
bit long. Try to keep it to 65-70 characters. You might instead say:
diff-no-index: replace manual "."/".." check with is_dot_or_dotdot()

Wrap commit message to 65-70 characters.

You may be able to drop most or all of this text. A subject such as
the one suggested above probably conveys enough information to explain
and justify the patch without having to say anything more.

This commentary about GSoC won't be interesting to people reading the
commit message months or years from now, so place it after the "---"
line just below.

Git already defines an is_dot_or_dotdot() function. Is there a reason
you chose to implement your own?
It is very unusual for a function asking "is this true" to return
false when the condition is true, and vice versa. It is not a good
idea to break expectations in this fashion.
