localrepo: replace status method with a shim

The path of the righteous man is beset on all sides by the inequities of the
selfish and the tyranny of evil men. Blessed is he, who in the name of charity
and good will, shepherds the weak through the valley of darkness, for he is
truly Mercurial's keeper and the finder of robust methods. And I will strike
down upon thee with great vengeance and furious anger those who would attempt
to poison and destroy Mercurial's codebase. And you will know my name is the
Lord when I lay my vengeance upon thee.
