That feels wrong to me; would we really want a list of "$OUTSIDE_PROJECT
uses this" against all methods?  CGit is using Git's internal API and so
should be prepared for breakage and to do what is necessary to work
around it - it's just this one case where adding a 2 line function to
Git makes CGit's life a lot easier.

I would hope that having this message in the history should be enough to
prevent this changing in the future; and it means that the comment is
associated with a date so that someone can decide to check whether CGit
is still using this function in the distant future.
