Wrong variable value with some variable names

[ivnmaksimovic]

If I use varible names that start the same like $my-color and $my-color-light, $my-color-light value will be wrong.

// Colors
//
// Some description
//
// markup:
// <div style="background: {$modifiers};" class="styleguide-color">{$modifiers}</div>
//
// $my-color             - My color.
// $my-color-light       - My light color
//
// Styleguide 2.1
$my-color: #990000;
$my-color-light: #ff0000;

will result in $my-color-light rendered like this: <div style="background: #990000-light;" class="styleguide-color">#990000-light</div> instead of <div style="background: #ff0000;" class="styleguide-color">#ff0000</div>
