[EXIM] Macros and transport/director/router instance names

I have an appendfile transport that spools in mailstore_format to a
special directory where another program later picks up the files for final
delivery. For logging reasons I want the name of the transport to be the
same as the name of the directory, but I want to be able to change the
name of the directory if necessary.

So I thought I could use a macro in the config file as excerpted below,
but to my great surprise the macro is NOT expanded in the lines ending
with `:' that name the transport, director, and router instances; so exim
dies with

1999-01-29 12:48:46 Exim configuration error
outbound transport, referred to in line 405, was not found

I can of course live without this, but it'd be nice if the documentation
didn't say that "all subsequent lines in the file" are macro-replaced.

-----------

SPOOLER = outbound

# Transports

SPOOLER:
driver = appendfile
directory = /var/spool/SPOOLER
create_directory
directory_mode = 0770
mode = 0660
group = mail
mailstore_format

end

# Directors

SPOOLER:
driver = localuser
transport = SPOOLER
verify = false

end

# Routers

SPOOLER:
driver = domainlist
transport = SPOOLER
route_list = <...>
verify = false

end
