.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

+The cursor position does
+not change (after moving to \fIy\fP, \fIx\fP, 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.

+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
