 .SH DESCRIPTION
 These routines return a NULL-terminated array of \fBchtype\fR quantities,
 starting at the current cursor position in the named window and ending at the
-right margin of the window.  The four functions with \fIn\fR as
+right margin of the window.
+The four functions with \fIn\fR as
 the last argument, return a leading substring at most \fIn\fR characters long
 (exclusive of the trailing (chtype)0).
 Constants defined in \fB<curses.h>\fR can be used with the \fB&\fR (logical
