When we emit `#\ ` for a Space character to a pretty stream, note in the pretty stream that the trailing space is significant, so that outputting a line with that text at the end does not delete that trailing space. SB-PRETTY:NOTE-SIGNIFICANT-SPACE is defined and exported (from an internals package) in order to be the answer to "how can user-defined pretty printing routines do this?" Fixes lp#1985814
