revlog: use raw content when building delta Using external content provided by flagprocessor when building revlog delta is wrong, because deltas are applied to raw contents in revlog. This patch fixes the above issue by adding "raw=True". test-revlog-raw.py now shows "local test passed", but there is more to fix.
