revert: properly revert to ancestor of p2 during merge (issue5052)
During merge, added (from one perspective) file can be reported as "modified".
To work around that, revert was testing if modified file were present in the
parent manifest and marking them as "added" in this case. However, we should be
checking against the target revision manifest instead. Otherwise see file as
"newly added" even if they exist in the target revision.
That revert behavior regressed in 06fbd9518bc5.
