Slash hack bug

[klimashkin]

Some css hacks lead to unexpected results:

For example, such bootstrap class:

// Position radios and checkboxes better
input[type="radio"],
input[type="checkbox"] {
  margin: 4px 0 0;
  margin-top: 1px \9; /* IE8-9 */
  line-height: normal;
}

Becomes:

input[type="radio"],input[type="checkbox"]{margin:1px 0 0;line-height:normal}
