I think the above code segment code will probably work better as:

	# put target after local address
	echo "-> `tr '[\015\012]' \\040 < $forward`" >> ~/alladdresses

You can sed/awk/tr away any characters you need to.  The text above would 
translate EOLs (CR, LF, CRLF) into white space, collapsing the entire file 
onto one line; it does need to be within the context of the echo command, 
however, of you'll not have an EOL on the line in ~/alladdresses.

Play with your backslashes; I may have the wrong number for your shell.
