(trivial-gray-streams:stream-line-column stream)
Function: Return the column number where the next character will be written, or NIL if that is not meaningful for this stream. The first column on a line is numbered 0. This function is used in the implementation of PPRINT and the FORMAT ~T directive. For every character output stream class that is defined, a method must be defined for this function, although it is permissible for it to always return NIL.
