title: VIM 80 Column Highlight for specific filenames
body: <p>I know how to highlight past 80 characters using vim for all of my files using the following in my vimrc:</p>
  
  <pre><code>if exists('+colorcolumn')
    set colorcolumn=80
  else
    au BufWinEnter * let w:m2=matchadd('ErrorMsg', '\%&gt;80v.\+', -1)
  endif
  </code></pre>
  
  <p>But is there a way to apply this to only certain file names? I am somewhat familiar with the autocmd but I can't seem to make it work. I don't want it to apply to file TYPES, but only a certain file name. Thanks.</p>
