filter-branch: add git_commit_non_empty_tree and --prune-empty.
git_commit_non_empty_tree is added to the functions that can be run from commit filters. Its effect is to commit only commits actually touching the tree and that are not merge points either. The option --prune-empty is added. It defaults the commit-filter to 'git_commit_non_empty_tree "$@"', and can be used with any other combination of filters, except --commit-hook that must used 'git_commit_non_empty_tree "$@"' where one puts 'git commit-tree "$@"' usually to achieve the same result.
