You have a corrupt patch, and "git-apply" not only tells you so, it tells you _exactly_ where it is:

In particular, it has whitespace damage at line 10:

And take a close look. That line should have _one_ space on it (the space that says "neither new nor old"), and it's totally empty (well, now in my email it has "10 " on it, of course ;)

Btw, you have another problem: you should add a "---" marker to before the patch header, otherwise your commit message will have the "diff -urpN" thing in it. To the "dotest" scripts, "---" is the thing that says "here ends the message and the patch begins".

(The line numbers from "git-apply" will also start at that --- point, so if you add a "---" just above the "diff" line, you'd get "line 12" being the corrupt one)
