largefiles: walk history in ascending order while downloading all lfiles I don't think the order matters. Maybe it's purely because of the use of walkchangerevs(), which was originally designed for "hg log" command. Surprisingly, the number of objects fetched in test-largefiles.t has changed. According to the --verbose output, the order of the following fetches flipped and the latter got deduplicated. getting large3:eb7338044dc27f9bc59b8dd5a246b065ead7a9c4 found eb7338044dc27f9bc59b8dd5a246b065ead7a9c4 in store getting sub/large4:eb7338044dc27f9bc59b8dd5a246b065ead7a9c4 found eb7338044dc27f9bc59b8dd5a246b065ead7a9c4 in store

largefiles: replace use of walkchangerevs() with simple revset query Since it does nothing in prepare(), what we're doing is just walking revisions matching ".hglf" in reverse order.
