pic: new feature: digit-separating commas.
This allows for pic patterns like #,###,###.### which incorporate digit separating commas into the output. * stdlib/pic.tl (comma-positions, insert-commas, expand-pic-num-commas): New system functions. (expand-pic): Recogize comma as a character which can be escaped using the tilde. Recognize a more complicated numeric pattern with commas. If the matched token contains commas, treat it using expand-pic-num-commas. (pic): Propagate a copy of the new numeric pattern here, where it is used for separation into tokens. * txr.1: Documented.
