In some use case that the mapping rules need backtracking and the
non-matched rule has star(s), the fsm will incorrectly return the
captures from latter non-matched rule.
This PR fixes this by copying the current
captures
slice to a differentslice and only return the copied slice. So that later assignment to
captures
won't affect the captures of a previously matched rule.Fix #168
