Not update the indices

[STAR0903]

Hello, I encountered some issues while learning the code. If my understanding is incorrect, I apologize in advance for the trouble. In the insertChild() method of the tree.go file, in the processing branch of the parameter node (param), when there are subpaths after the wildcard, the code creates a new child node but does not update the indices. Moreover, it seems that all the generated child nodes after entering this method have the same fullpath.

// if the path doesn't end with the wildcard, then there
// will be another subpath starting with '/'
if len(wildcard) < len(path) {
	path = path[len(wildcard):]
	child := &node{
		priority: 1,
		fullPath: fullPath,
	}
	n.addChild(child)
	n = child
	continue
}
