Ah, I overlooked the part that escaping is required for carets and 
simply thought you were referring to the parentheses. Thanks for 
pointing it out.

Please at least make your parser warn about incorrect texture string 
escaping. IMO the result of misinterpreting/overlooking the spec should 
not go unnoticed (unless it works around a bug, of course, which is 
unfortunate).

In any case, your effort on this patch is appreciated, and I will as 
well take some time improving the HUD code.
