.in should be set to 0 when the diversion is output (or an environment with .in 
0 should be used), else there is indeed double indent.

Indent is part of the line length. If line length is 4i, indent is 1i and text 
(folowing the indent) is 3.5i I had expected \n(dl to be 4.5i which should 
trigger the error message...(?)
