Actually, it eats both newlines... The trailing newline that still
appears is from "echo" command, which appends a newline by default.
Try:

echo -n "$foo" | hexdump -C

instead. Anyway, this is from "man bash":

"Command Substitution
[...]
Bash performs the expansion by executing command and replacing the
command substitution with the standard output of the command, with any
trailing newlines  deleted. Embedded newlines are not deleted, but
they may be removed during word splitting."

So I suppose this is an expected behaviour.
