Sublime Text 2: diff syntax highlighting with a light background color scheme

I recently discovered a new text editor, Sublime Text 2, which I quite like. By default it uses a dark-background color scheme, and while it comes with a few light schemes, none of them have proper syntax highlighting for "diff" files. Fortunately it turned out to be easy to fix:
  1. cd into the Packages/Color Scheme - Default directory.
  2. Copy the scheme you like, e.g. cp iPlastic.tmTheme iPlastic-my.tmTheme.
  3. Change the new file as follows.
  4. To change the theme, edit your preferences file to say
    "color_scheme": "Packages/Color Scheme - Default/iPlastic-my.tmTheme",
    To see the effect of your changes, just save the preferences file.
