I've made this change.

As an interim solution, I've adopted _update-info-dir, and updated it to 
contain this script.

This removes the last use of autodep, which unblocks some further 
improvements to upset.

Future work: I can't see any reason why this script now needs an 
independent existence, so it could be absorbed by the info package.
