I know this wasn't introduced by this change, but this segment of the test seems broken to me. s = buf means that they are pointing to the same buffer in memory, so of course buf.slice(i) and s.slice(i) are going to be the same thing. Maybe that's the point of the test? But I suspect not. Anyone understand this? Worth just removing this entire block? If not, it seems like it could use a comment.

This segment was imported in this commit by @jasnell a year ago. I'm also confused with it.
@jasnell Could you tell us something about it ?

@starkwang I don't think that's the commit that introduced it. It's s = buf.toString() in that commit, which is very different from s = buf.
It appears that it was introduced in 02a4c08 and that it was an error. Does it make sense to add a second commit here or else in a different PR to restore it to buf.toString()?

@Trott I believe it should be buf.toString() as well, the s probably means "string" here (would be clearer if it gets renamed to str). Fixing it here SGTM.

OK, I'll change it into buf.toString().
