numbered buffers may be allocated by applications through the \fBnbuf\fR
argument of (see \fBform_field_new\fR(3X)) but are not manipulated by the forms

+Please note that this buffer has always the length of the buffer, that means
+that it may typically contain trailing spaces. If you entered leading spaces
+the buffer may also contain them. If you want the raw data, you must write your
+own routine that copies the value out of the buffer and removes the leading
+and trailing spaces. Please note also, that subsequent operations on the form
+will probably change the content of the buffer. So do not use it for long term
+storage of the entered form data.
