revset: make revsbetween public This patch is part of a series of patches to speed up the computation of revset.revsbetween by introducing a C implementation. The main motivation is to speed up smartlog on big repositories. At the end of the series, on our big repositories the computation of revsbetween is 10-50x faster and smartlog on is 2x-5x faster. Later in this serie, we want to reuse the implementation of revsbetween in the changelog module, therefore, we make it public.

match: fix a caseonly rename + explicit path commit on icasefs (issue4768) The problem was that the former name and the new name are both normalized to the case in dirstate, so matcher._files would be ['ABC.txt', 'ABC.txt']. localrepo.commit() calls localrepo.status(), passing along the matcher. Inside dirstate.status(), _walkexplicit() simply grabs matcher.files() and processes those items. Since the old name isn't present, it is silently dropped. There's a fundamental tension here, because the status command should also accept files that don't match the filesystem, so we can't drop the normalization in status. The problem originated in baa11dde8c0e. Unfortunately with this change, the case of the old file must still be specified exactly, or the old file is again silently excluded. I went back to baa11dde8c0e^, and that had the same behavior, so we are no worse off. I'm open to ideas from a matcher or dirstate expert on how to fix that half.
