Attempt to yield names in sorted order when walking.
This is an improvement in behaviour, but the walk and changes code still
has some flaws that make sorted name presentation difficult:
- changes returns tuples of names, instead of a sorted list of (name,
status) pairs.
- walk yields deleted names after all others.
