This is an artifact of entering in code manually in the shell, which
normally would have more cues to go on.  In a script it would no that
these two statements were unrelated; in the interactive interpreter it
can't be sure so is waiting for a blank link to separate them.  You can
tell this when the prompt is ... instead of >>>.
