.SH DESCRIPTION
The function \fBnew_fieldtype\fR creates a new field type usable for data
-validation. You supply it with \fIfield_check\fR, a predicate to check the
+validation.
+You supply it with \fIfield_check\fR, a predicate to check the
validity of an entered data string whenever the user attempts to leave a field.
The (FIELD *) argument is passed in so the validation predicate can see the
field's buffer, sizes and other attributes; the second argument is an
The function \fBfree_fieldtype\fR frees the space allocated for a given
validation type.
.PP
-The function \fBset_fieldtype_arg\fR associates three storage-management functions
-with a field type.
+The function \fBset_fieldtype_arg\fR associates

The \fImake_arg\fR function is automatically applied to the
list of arguments you give \fBset_field_type\fR when attaching validation
to a field; its job is to bundle these into an allocated argument-block
\fB(void *)\fR. The type has been left uncorrected for strict compatibility
with System V.
