Atualização 2012 : agora eu realmente recomendo verificar o vim-powerline que substituiu meu antigo script de linha de status, embora atualmente não haja alguns recursos que eu sinto falta.
Eu diria que o material da linha de status no meu vimrc foi provavelmente o mais interessante / útil do momento (extraído dos autores vimrc aqui e da postagem do blog correspondente aqui ).

Entre outras coisas, ele informa sobre a linha de status das informações de arquivo padrão usuais, mas também inclui itens adicionais, como avisos para: colar conjunto, recuo misto, espaço em branco à esquerda etc.
Além disso, e como mostrado na captura de tela, combiná-lo com o
sintático permite destacar quaisquer erros de sintaxe (assumindo que o seu idioma de escolha tenha um verificador de sintaxe associado incluído.
