Hi.
  The following DASH behaviour seems buggy to me

-----------------
$ export A='\n'
$ echo $A

$
-----------------

whereas using BASH would result in printing literally \n .

I.e. presumingly DASH does secondary interpolation of escaped
symols in values of environment variables. 

Please CC me with replies, I am not in the list.

Thanks, regards,
  Dima.

P.S.
  Wrom the other hand

$ export B=1
$ export A='$B'
$ echo $A
PRINTS $B
$
