Hi,

I agree that your patch fixes a long-time issue.

I know that "sizeof filename" works, but in git.git, `git grep sizeof' returns > 700 instances, only 23 of which do not use the "sizeof(filename)" form. It's just a style issue, but I prefer the latter nevertheless...

not make this:

> +		return error("Patch pathname too long");

unnecessary for the case that there _was_ an output directory specified? I'd make that an "else if"... But I might be missing something.
