#2 Incorrect Highlighting when next to alhpa characters

[Peter Jordan Labun]

Words that should highlight fail to do so when they are
typed next to characters A-Z, 1-0 and a-z. Next to
white space and other chacters is fine.

For example:
function test() {
var a = 1;

b = a + 1;
}

If I change the line "b = a +1;" to "this.b = a + 1 in this
order this will fail to highlight.

b = a + 1;
thisb = a + 1;
this.b = a + 1; // When I insert the period b
// should highlight but it doesn not

This happens with all words that are highlighted.
