No, I think that's ok (apart from: I couldn't apply the patch, due to
some whitespace difference I guess, and apart from: the patch should
have been relative to the toplevel directory -- always having to cd or 
to type paths when patch asks which file to patch is a bit annoying).

Due to the way such matches are (or should be) printed, the `1 +' was
indeed wrong, just the same as the line two lines above the one you
changed.

Bye
