status: back out changeset 89f49813526c
This backs out 89f49813526c (status: change + back out == clean (API),
2016-01-04). Although correct, it turned out that it was just too
slow. For example, 'hg status --rev .~1000 --rev .' on the Mozilla
repo went from <1s to >30s on cold disk. So we go back to reporting
reverted changes as modified instead of clean. These are rare anyway,
as suggested by the fact that it had been broken since before
Mercurial 2.0.
