This routine is used prevent command output data from scrolling off the end

If the use hits Q to quit return TRUE else for any other key return FALSE.
PrefixNewline is used to figure out if a newline is needed before the prompt
string. This depends on the last print done before calling this function.
CurrentRow is updated by one on a call or set back to zero if a prompt is
needed.
