phabsend: make --amend the default The local tag feature was intended to make `phabsend` closer to `email` workflow. But its experience is not great in multiple ways: - after rebase, obsoleted changesets are still visible because of tags - without obsstore, the association information will get lost - even with obsstore, things could go wrong with graft, export+import - no easy way to tell which Differential Revision a commit is associated Therefore make `--amend` the default. People wanting the old behavior can use `--no-amend`. Differential Revision: https://phab.mercurial-scm.org/D511

record: make the m key open an editor for the commit message (issue5667) With the former crecord extension, the user could edit the commit message while he was de-/selecting hunks. By pressing 'm', an editor showed up to edit the commit message. With record being part of mercurial, this feature is not available anymore. However, the help text still mentions it. As the infrastructure needed is still present, this feature is quite easily ported from the crecord extension to mercurial. It seems there is no test coverage for record ui, so I tested this patch manually on my local machine.
