Arguments and Values

Description

terpri outputs a newline to output-stream.

fresh-line is similar to terpri but outputs a newline only if the output-stream is not already at the start of a line. If for some reason this cannot be determined, then a newline is output anyway. fresh-line returns true if it outputs a newline; otherwise it returns false.
