Add the %abs() function, to produce the absolute value as an always-positive decimal constant. Change the order of the arguments for %num(). Refactor the handling of optional arguments, to reduce the amount of redundant code. This is currently only used for builtin functions, but might be extended in the future. Signed-off-by: H.
