title: Vim editor indent problem when the first character of the line is a sharp # character
body: <p>This haven been bugging me since the first day using Vim for 3 years. Whenever I try to indent a line via <kbd>Shift</kbd> + <kbd>></kbd> when the FIRST CHARACTER of the line starts with a "#", it doesn't work at all, regardless of the file types (.php, .txt, etc.). Because # is used for comment in PHP and I also use it for decoration for text files something like:</p>
  
  <pre># This is a comment
  
  ### 1. Instruction one
  
  # ------------ this is an sample --------------</pre>
  
  <p>I use Vim 7.2 in Ubuntu with the following <code>.vimrc</code> settings</p>
  
  <pre><code>syntax on
  set t_Co=256
  set incsearch
  set hlsearch
  set number
  set nowrap
  set nowrapscan
  set ignorecase
  set et
  set sw=4
  set smarttab
  set smartindent
  set autoindent
  set textwidth=0
  set noequalalways
  set formatoptions=1
  set lbr
  set vb      
  set foldmethod=marker
  </code></pre>
  
  <p>Thanks!</p>
