Maybe a dumb question (I don't understand a lot of the regex code!)
but is it correct to set this to 1 in the case where
__rep_count.first != _M_current ? Could that result in the count
going downwards from 2 to 1? (Maybe that's correct?)
As I said in the comment, __rep_count records how many times
(__rep_count.second) this node is visited *under certain input
iterator* (__rep_count.first).
That is to say, if the current iterator (_M_current) is not changing,
but the executor keeps visiting this node, times of visit needs to be
recorded. Once the _M_current changed, the count should be reset to 0.
We simply set it to 1 for the "set to 0 then increase by 1"
operations.
