rule with multiple lines

[Nicola Piazzi]

Is there a way to have multiple line in a single rule ?

For example :
meta            OW_SENT_EMAIL         ( OW_T_SENT_EMAIL && ! OW_T_REF_EMAIL && 
! OW_T_REF_FULL && ! OW_REF_THIS && OW_PASS)

Will be better :
meta            OW_SENT_EMAIL         ( OW_T_SENT_EMAIL
                                                                      && ! 
OW_T_REF_EMAIL 
                                                                      && ! 
OW_T_REF_FULL 
                                                                      && ! 
OW_REF_THIS 
                                                                      && 
OW_PASS)
