/**
* Returns the string, with after processing the following backslash escape sequences.
*
* attacklab: The polite way to do this is with the new escapeCharacters() function:
*
* text = escapeCharacters(text,"\\",true);
* text = escapeCharacters(text,"`*_{}[]()>#+-.!",true);
*
* ...but we're sidestepping its use of the (slow) RegExp constructor
* as an optimization for Firefox. This function gets called a LOT.
