git-mv: keep git index consistent with file system on failed rename

git-mv: keep git index consistent with file system on failed rename

[Josef Weidendorfer]

When doing multiple renames, and a rename in the middle fails,
git-mv did not store the successful renames in the git index;
this is fixed by delaying the error message on a failed rename
to after the git updating.

This is actually independent from the just sent patch, but
the context lines shows it applied...
