Documentation: filter-branch: show --ignore-unmatch in main index-filter example
Rearrange the example usage of
git filter-branch --index-filter 'git rm --cached ...'
so that --ignore-unmatch is in the main example block. People keep
stumbling over the (lack of this) option to the point where it is a
FAQ, so we would want to expose the most common usage where it stands
out.
