title: MacVim gets all settings from ~/.vimrc, but not the colors and I have to source it again
body: <p>I am using the following ~/.vimrc with MacVim 7.4 on MacOS X Mavericks:</p>
  
  <pre><code>set guifont=Menlo:h14
  set encoding=utf8
  set mouse=a
  set expandtab
  set ts=8
  set showcmd
  set nocompatible
  set backspace=2
  set viminfo='20,\"50
  set history=50
  set ruler
  set si
  set hlsearch
  syntax on
  set bg=light
  hi Cursor     term=inverse   ctermfg=black                guifg=black  guibg=green
  hi Visual     term=inverse   ctermfg=yellow ctermbg=black guifg=yellow guibg=black
  hi Comment    term=inverse   ctermfg=grey   ctermbg=black guifg=white  guibg=black
  hi Identifier term=NONE      ctermfg=black                guifg=black
  hi Constant   term=underline ctermfg=darkred              guifg=red
  hi Statement  term=bold      ctermfg=blue                 guifg=blue
  hi PreProc    term=NONE      ctermfg=black                guifg=black  gui=underline
  hi Special    term=NONE      ctermfg=black                guifg=black
  hi Type       term=bold      ctermfg=blue                 guifg=blue
  </code></pre>
  
  <p>and can see that the editor takes all the settings from that file (the font family and its size, the show ruler and tab settings, ...), but not the colors:</p>

  <p>Only after I issue the command <code>:so ~/.vimrc</code> does it take my color settings too (red and blue with inverted comments):</p>

  <p>Does anybody please know, what is happening, why doesn't MacVim pick up the syntax colors too?</p>
