I don't at all insist upon it, but this behavior change feels somewhat
like it ought to be in its own commit. I'm also not convinced that
making this consistent with the less forgiving behavior of
"interactive adding" is desirable (rather the reverse: that that case
should be more flexible). However, I wasn't following the discussion
with Junio closely, and perhaps missed you two agreeing that this is
preferable.
