 .SH DESCRIPTION
 These functions make it possible to set hook functions to be called at various
 points in the automatic processing of input event codes by \fBform_driver\fR.
-
+.PP
 The function \fBset_field_init\fR sets a hook to be called at form-post time
 and each time the selected field changes (after the change).  \fBfield_init\fR
 returns the current field init hook, if any (\fBNULL\fR if there is no such
 hook).
-
+.PP
 The function \fBset_field_term\fR sets a hook to be called at form-unpost time
 and each time the selected field changes (before the change).  \fBfield_term\fR
 returns the current field term hook, if any (\fBNULL\fR if there is no such
 hook).
-
+.PP
 The function \fBset_form_init\fR sets a hook to be called at form-post time and
 just after a page change once it is posted.  \fBform_init\fR returns the
 current form init hook, if any (\fBNULL\fR if there is no such hook).
