+ SVr4 specifies only "an integer value other than <STRONG>ERR</STRONG>" as a successful
+ return value.
+
+ SVr4 indicates that the optimization of physically scrolling
+ immediately if the scroll region is the entire screen "is" performed,
+ not "may be" performed. <EM>ncurses</EM> deliberately does not guarantee that
+ this will occur, to leave open the possibility of smarter optimization
+ of multiple scroll actions on the next update.
+
+ Neither SVr4 <EM>curses</EM> nor X/Open Curses specify whether the current
+ attribute or current color pair of blanks generated by the scroll
+ function are zeroed. <EM>ncurses</EM> does so.
