Both solutions are fine and I realize I'm a bit late to the party as you posted the original patch almost 3 weeks ago, so I don't want to delay it any longer. I think it's just a matter of deciding whether to enforce the buffer size limit using buffer_size or buffer_end. As the first option involves a little bit less writing, I thought I'd suggest it.

Don't worry, I understood your intentions from the commit message, so I don't think it's worth posting a v3 only to correct minor stylistic errors.
