peer: subrepo isolation, pass repo instead of repo.ui to hg.peer Do not pass ui because it contains the configuration of the repo. It is the same object as repo.ui. When a repo is passed to hg.peer, the global configuration is read from repo.baseui.

subrepo: isolate configuration between each repositories in subrepo tree Before this patch, repository local configurations are not isolated between repositories in subrepo tree, because "localrepository" objects for each subrepositories are created with "ui" instance of the parent of each ones. So, local configuration of the parent or higher repositories are visible also in children or lower ones. This patch uses "baseui" instead of "ui" to create repository object: the former contains only global configuration. This patch also copies 'ui.commitsubrepos' configuration to commit recursively in subrepo tree, because it may be set in not "repo.baseui" but "repo.ui".
