How is this in disagreement with what Jason said? His point is that
if you're in the module "a/b/c", "./controllers" refers to
"a/b/controllers", and "backbone" refers to "backbone". Once you have
a module name, there's a default resolution semantics to produce a URL
for the fetch hook, which you describe accurately.
