tests: vcs: remove influence of user's hg settings Certain settings in the user's hgrc file can cause test failures. For example, enabling a non-existent extension prints stderr messages like *** failed to import extension journal: No module named journal Tests that check stderr output for emptiness, like test_clone_hg_repo_by_admin, then fail. Instead, avoid all influence of the user's settings, by setting HGRCPATH and HGPLAIN to empty. In versions of Mercurial before 4.2, setting an empty HGRCPATH was generally enough to get expected behavior, but since 4.2 the behavior of some commands has changed, and a pager is now default. Setting HGPLAIN is a simple way of neutralizing even that.
