Summary:
?now can take any character as input, as well as detect EOF.Motivation:
?"!?'".Previous behaviour
?would repeat the last character in the stream if it ran out of characters to consume. Furthermore, it would skip certain characters (such as linefeeds) when processing input. Whether or not this was by design is unclear.Implemented behaviour
?takes 1 raw character of input using the methodgetchar()inherited from C. When encountering EOF,?will set the current cell to0.
