This function allows you to combine two separate routes into one. This is
different from combining them in a routestack, because a request is only
matched to one handler in each route (thus combining them with
route_merge() will ensure only one handler is called).
Usage
route_merge(x, route, use_root = TRUE)
Value
x with route merged into it
Arguments
x, route
Route objects to merge. route will be merged into x
use_root
Should the root of route be added to all its paths before
it is merged into x
