revlog: make _addrevision only accept rawtext All 3 users of _addrevision use raw: - addrevision: passing rawtext to _addrevision - addgroup: passing rawtext and raw=True to _addrevision - clone: passing rawtext to _addrevision There is no real user using _addrevision(raw=False). On the other hand, _addrevision is low-level code dealing with raw revlog deltas and rawtexts. It should not transform rawtext to non-raw text. This patch removes the "raw" parameter from "_addrevision", and does some rename and doc change to make it clear that "_addrevision" expects rawtext. Archeology shows 2df983125d37 added "raw" flag to "_addrevision", follow-ups e12c0fa1f65b and c1b7b2285522 seem to make the flag unnecessary. test-revlog-raw.py no longer complains.
