git reports this patch as corrupted and claims it was hand-edited.
Looking into it, there is an extra space in unchanged lines of code.
Indeed, it applies cleanly after replacing douple spaces at the beginning
of each line with a single space.

No idea how that happened, but please be careful whend sending patches.

Applied.
