Title: Add missing leading slash when canonicalising

This means that for a path-like input such as:
first-level/second-level

we no longer trash it to make:
/second-level

we instead make it into:
/first-level/second-level

On the other hand it does mean that other things accidentally pasted into a
paths field will be turned into paths...
