title: Indentation with "#." start of paragraph
body: <p>When I type "1. blah blah blah" VIM recognizes the "1." prefix and it indents the rest of the paragraph tidy.</p>
  
  <p>I would like to configure VIM to do the same thing with "#." literal prefix, since ReST files autonumbers the paragraphs when started with "#.".</p>
  
  <p>Help!.</p>
