verify: update comment to say that lfs doesn't need fulltext to check renames The reason is that `filelog.renamed()` indirectly calls `filelog.revision()`, which is what accesses the full text. However, LFS wraps `filelog.renamed()` and completely handles the case where an LFS blob is in play by using rawdata. I've got a test to demonstrate that this is the case, and prevent regressions. But the `skipread` flag is set on all lfs revisions when using `--no-lfs`, regardless of whether or not the blobs are local. Just above this, that flag is consulted, causing the rename checks to be skipped. That will need to be loosened up first. Differential Revision: https://phab.mercurial-scm.org/D7709
