The documentation does not come out directly and say this but in several
places it mentions applications of the pipe transport where the arguments
are tokenized BEFORE shell expansion or execution. (Look at
restrict_to_path and .forward expansion). It runs the command directly
with out giving it to a command shell. Because exim is parsing the line
by it's rules and not giving it to a shell, you should not have to worry
about setting an Input Field Separator.
