histedit: removing the experimental config 'histeditng' This config has been around for about 2 years now. So, it can be assumed to be stable. Therefore, I am removing the config. This also makes the test 'test-histedit-base.t' compatible with chg. Test Plan: - Ran the test 'test-histedit-base.t' with and without '--chg' option. - Ran all the other tests without '--chg' option. - Checked the output of 'hg help histedit'.

convert: fix the RevisionSpec import in the bzr module This import was failing (because its invalid) which was resulting in the following tests failing with chg running: - test-convert-bzr.t - test-convert-bzr-directories.t - test-convert-bzr-ghosts.t - test-convert-bzr-treeroot.t - test-convert-bzr-114.t - test-convert-bzr-merges.t This commit fixes the import which in turn fixes the tests. Test Plan: Ran the aforementioned tests with and without '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D936
