log: speed up hg log <file|folder> This patch makes hg log <file|folder> faster by using changelog.readfiles instead of changelog.read. On our large repos for hg log <file|folder> -l5 operations that were taking: - ~8s I see a 25% improvement - ~15s, I see a 35% improvement For recently modified folder/file, the difference is negligible as we don't have to consider many revisions.
