3233 - change how Mu escapes strings
Thanks Sam Putman for helping think through this idea. When you encounter a backslash, strip it out and pass through any following run of backslashes. If we 'escaped' a single following character like C, then the character '\' would be the same as: '\\' escaped once '\\\\' escaped twice '\\\\\\\\' escaped thrice (8 backslashes) ..and so on, the number of backslashes doubling each time. Instead, our approach is to make the character '\' the same as: '\\' escaped once '\\\' escaped twice '\\\\' escaped thrice ..and so on, the number of backslashes merely increasing by one each time. This approach only works as long as backslashes aren't also overloaded to create special characters. So Mu doesn't follow C's approach of overloading backslashes both to escape quote characters and also as a notation for unprintable characters like '\n'.
