Wait. This does not fix
git -c diff.colormovedws=nonsense diff
that dies with an error message---it should ignore the config and at
moat issue a warning.
The command line handling of
git diff --color-moved-ws=nonsense
does correctly die, but it first says "error: ignoring" before
saying "fatal: bad argument", which is suboptimal.
So, not so excellent (yet) X-<.
