Fixes #3745
Basically I was doing
range segmentsthen modifyingsegmentsso we had a couple of bugs going on. Panic if a matcher segment was ever the last thing in a route, and bad parsing (skipped segments) in other situations.Fixed by using a regular step loop and rewinding one step every time we splice a segment out.
