Subject: [PATCH] getArgs() now accepts curly braces as arg delimiters, which
 allows us to include spaces in arguments. "print 80" and "print {80}" are
 equivalent, but "print 80 + 1" and "print {80 + 1}" are not (the former
 counts as 3 arguments, the latter only one).

Actually, I haven't tied the YaccParser to getArgs() yet, so both would
still be errors. I still need to fix the segfaults on parse error.
