- Fix bug in unification not taking into account the right meta
substitution. Makes unification succeed a bit more often, hence auto
works better in some cases.
- Backtrack the changes of auto using Hint Unfold to do more delta and add
a new tactic "new auto" which does that, for compatibility.
The first fix may have a big impact on the contribs, whereas the second
should make them compile again... we'll see.
