Well yes, since those are the only ones that specify commands to be run,
and it is in that situation that Exim splits the line up into arguments
before doing expansions. The point of doing this is so that the result
of an expansion cannot change the number of arguments. Otherwise you run
the risk of screwing up the command when some rogue data arrives in a
message.
