summary: move the parents phase marker to commit line (issue4688)
The phase of the pending commit depends on the parent of the working directory
and on the phases.newcommit configuration.
First, this information rather depend on the commit line which describe the
pending commit.
Then, we only want to be advertised when the pending phase is going to be higher
than the default new commit phase.
So the format will change from
