Variable name is not encoded correctly

[omelancon]

In some very specific cases which I was unable to pinpoint exactly, variable names are not encoded correctly in the target bundle. Example:

test.html:

<script src="test.js"></script>

test.js

function ( nl ) {
  var nl = 1;
}

Result of inline test.html:

<script>function (~~s
s~~) {
  var~~s
s~~= 1;
}</script> 

The sequence of characters " nl " (spaces included) is converted to "~~s\ns~~" which is not a valid syntax.
