recover: don't verify by default

The reason is:
- it's not that hard to trigger interrupted transactions: just run out
  of disk space
- it takes forever to verify on large repos. Before --no-verify, I
  told people to C-c hg recover when the progress bar showed up. Now I
  tell them to pass --no-verify.
- I don't remember a single case where the verification step was
  useful

This is technically a change of behavior. Perhaps this would be better
suited for tweakdefaults?
