No, the function skips the delimiter too. It is slightly more practical for
the use case "parse all the key=value pairs in the whole string".

The delimiter can be found with ropts[-1], but it does not work if the key
is omitted and the value is empty. But an empty key can also be escaped.
Therefore, if someone wants to know the delimiter, they need to save the old
value of ropts.
