 .SH DESCRIPTION
-.SS overlay, overwrite

 The \fBoverlay\fP and \fBoverwrite\fP routines overlay \fIsrcwin\fP on
 top of \fIdstwin\fP.
 \fIscrwin\fP and \fIdstwin\fP are not required
@@ -63,21 +74,23 @@ If the argument \fIoverlay\fP is \fBtrue\fP,

 .SH RETURN VALUE
-Routines that return an integer return \fBERR\fP upon failure, and \fBOK\fP
-(SVr4 only specifies "an integer value other than \fBERR\fP") upon successful
-completion.
+These routines return the integer \fBERR\fP upon failure and an \fBOK\fP

 X/Open defines no error conditions.
 In this implementation,
 \fBcopywin\fP,
-\fBoverlay\fP and \fBoverwrite\fP return an error

 if either of the window pointers are null, or
 if some part of the window would be placed off-screen.
 .SH NOTES
 Note that \fBoverlay\fP and \fBoverwrite\fP may be macros.
 .SH PORTABILITY
-The XSI Curses standard, Issue 4 describes these functions (adding the const
-qualifiers).
+These functions are described in X/Open Curses, Issue 4,
+which adds \fI\%const\fP qualifiers to the arguments.
 It further specifies their behavior in the presence of characters
 with multibyte renditions (not yet supported in this implementation).
