It actually only strips the trailing newline. Any newlines in the middle
of the file are fine.
That's not what i'm seeing:
[stephan@host:~]$ echo -e "1\n2\n3"
1
2
3
[stephan@host:~]$ echo $(echo -e "1\n2\n3")
1 2 3
you would need echo "$(echo -e "1\n2\n3")" here to protect the embedded
newlines in the outer echo's output.... command expansion does not mess
with the newlines, really. as andy said, it strips only trailing ones.
