+
+       <STRONG>o</STRONG>   If the terminal has auto right margins, but also  has  capabilities
+           for  turning auto margins off and on, <EM>ncurses</EM> turns the auto margin
+           feature off temporarily when writing to the lower-right corner.
+
+       <STRONG>o</STRONG>   If the terminal has an insertion mode which can be turned  off  and
+           on,  <EM>ncurses</EM>  writes  the  character  just  before  the lower-right
+           corner, and then inserts a character to push the  update  into  the
