+ <STRONG>o</STRONG> The <EM>kill</EM> character (e.g., <STRONG>^U</STRONG>) erases the entire buffer, leaving the
+ cursor at the beginning of the buffer.
+
+ Characters input are echoed only if <STRONG>echo</STRONG> is currently on. In that
+ case, backspace is echoed as deletion of the previous character
+ (typically a left motion).
+
+ The <STRONG>getn_wstr</STRONG>, <STRONG>mvgetn_wstr</STRONG>, <STRONG>mvwgetn_wstr</STRONG>, and <STRONG>wgetn_wstr</STRONG> functions are
+ identical to the <STRONG>get_wstr</STRONG>, <STRONG>mvget_wstr</STRONG>, <STRONG>mvwget_wstr</STRONG>, and <STRONG>wget_wstr</STRONG>
+ functions, respectively, except that the <STRONG>*n_*</STRONG> versions read at most <EM>n</EM>
+ characters, letting the application prevent overflow of the input
+ buffer.
