Update to ncurses-4.2-990206:

    suppress sc/rc capabilities from terminal description if they appear
    in smcup/rmcup.  This affects only scrolling optimization, to fix a
    problem reported by several people with xterm's alternate screen,
    though the problem is more general.

 .SH NOTES
 Note that \fBaddch\fR, \fBmvaddch\fR, \fBmvwaddch\fR, and
 \fBechochar\fR may be macros.
-.SH EXTENSIONS
-The following extended \fBcurses\fR features are available only on PC-clone
-consoles and compatible terminals obeying the ANSI.SYS de-facto standard for
-terminal control sequences.  They are not part of XSI curses.
-
-The attribute A_ALTCHARSET actually forces literal display of PC ROM characters
-including the high-half graphics.  Your console driver may still capture or
-translate a few (such as ESC) but this feature should give you access to the
-card-suit characters, up and down-arrow, and most others in the range 0-32.
-(In a terminfo entry designed for use with \fBncurses\fR, the high-half
-characters are obtained using this attribute with an \fBacsc\fR string in
-which the second of each pair is a high-half character.)
-
-Giving \fBwechochar\fR an argument with its high bit set will produce the
-corresponding high-half ASCII graphic (SVr4 curses also has this feature but
-does not document it).  A control-character argument, however, will not
-typically produce the corresponding graphic; characters such as CR, NL, FF and
-TAB are typically interpreted by the console driver itself, and ESC will be
-interpreted as the leader of a control sequence.
 .SH PORTABILITY
 All these functions are described in the XSI Curses standard, Issue 4.
 The defaults specified for forms-drawing characters apply in the POSIX locale.
