title: sourcing vimrc when opening a file in tab page?
body: <p>I have a the following in my vimrc to highlight any lines that go past 80 columns:</p>
  
  <pre><code>highlight ColorColumn ctermfg=red ctermbg=bg
  call matchadd('ColorColumn', '\%81v.\+', 100)
  </code></pre>
  
  <p>It works great in most cases. However, I've noticed that if i open a file in a new tab, it doesn't work at all. I'm able to fix this by <code>:source $MYVIMRC</code>. But the issue is, when I source my vimrc I lose my indentLines plugin. I've done a little testing, and I have found that the indentLines goes away anytime the <code>vimrc</code> is sourced in an open instance of vim. Still, I am unable to determine why the 2 lines shown above are not being called when I open a file in a new tab. Any ideas?</p>
