 .SH DESCRIPTION
 These routines delete the character under the cursor; all characters to the
 right of the cursor on the same line are moved to the left one position and the
-last character on the line is filled with a blank.  The cursor position does
-not change (after moving to \fIy\fR, \fIx\fR, if specified).  (This does not
+last character on the line is filled with a blank.
+The cursor position does
+not change (after moving to \fIy\fR, \fIx\fR, if specified).
+(This does not
 imply use of the hardware delete character feature.)
 .SH RETURN VALUE
 All routines return the integer \fBERR\fR upon failure and an \fBOK\fR (SVr4
 specifies only "an integer value other than \fBERR\fR") upon successful
 completion.
+.PP
+Functions with a "mv" prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
 .SH NOTES
 Note that \fBdelch\fR, \fBmvdelch\fR, and \fBmvwdelch\fR may be macros.
 .SH PORTABILITY
