The peek_next method's doc comment incorrectly stated it accesses the
"previous" node when it actually accesses the next node. This commit
fixes the documentation to accurately reflect the method's behavior.

I shared a Reviewed-by tag for the first version, so please include it
in the commit message when sending a new version. That way, I don't have
to review the same code twice.

Also, this should say [PATCH v2] in the subject since it's version 2 of
this patch.
