\_e_q_n:

     This should not start a new paragraph: 1/(n-1).

\_d_e_q_n:

     1-arg form, centered also in text conversion:

                        theta = (mu^*, sigma^2, rho)                    
     
     2-arg form, where the text version is collapsed before centering
     (for the sake of existing Rd files):

                                  E = m c^2                             
     
     With AMS extension (R >= 4.2.2), where the text version spans more
     than 3 source lines (5 in fact) and is thus output as-is in R >=
     4.4.0:

                  0  if x < 0,
         f(x) =
                  1  if x >= 0.
