You have to adapt the line minimally: As is, it will possibly catch the 
wrong names, and it does not _move_ the directory, but rather _copy_ it.

So I think something like

git-ls-files -s | sed "s-\t-&newsubdir/-" |
  GIT_INDEX_FILE="$GIT_INDEX_FILE".new git-update-index --index-info &&
mv "$GIT_INDEX_FILE".new "$GIT_INDEX_FILE"

is needed.
