scmutil: fix systemrcpath regression introduced in f5dd179bfa4a Changeset f5dd179bfa4a introduced a 'root' path component to look for hgrc files, which is used both as an absolute path and a path relative to the <install-root>. The latter one was broken since 'root' was set to an absolute location and the subsequent os.path.join discarded the <install-root> path prefix.

revlog: fix partial revision() docstring (from d7d64b89a65c)

graphlog: fix --follow FILE and relative paths The situation is complicated because filelog() revset uses a match object in relpath mode while follow() revset interprets the filename as a manifest entry.

graphlog: reduce duplication in --follow code

graphlog: add all log options to glog command glog and log -G should be equivalent.

graphlog: implement --hidden

revert: add support for reverting subrepos without --no-backup and/or --all When a subrepo is reverted but --no-backup is not set, call revert on the subrepo that is being reverted prior to updating it to the revision specified in the parent repo's .hgsubstate file. The --all flag is passed down to the subrepo when it is being reverted. If the --all flag is not set, all files that are modified on the subrepo will be reverted.

revert: add support for reverting subrepos Reverting a subrepo is done by updating it to the revision that is selected on the parent repo .hgsubstate file. * ISSUES/TODO: - reverting added and removed subrepos is not supported yet. - reverting subrepos is only supported if the --no-backup flag is used (this limitation will be removed on another patch). - The behavior of the --all flag has been changed. It now reverts subrepos as well. Note that this may lead to data loss if the user has a dirty subrepo.
