xpg_echo doesn't change 'echo -ne' behavior
('echo -e' force backslash-escape sequences expansion independently)

$ shopt xpg_echo
xpg_echo        off
$ echo -e '\r\n' | od -tx1
0000000 0d 0a 0a
0000003
$ shopt -s xpg_echo
$ shopt xpg_echo
xpg_echo        on
$ echo -e '\r\n' | od -tx1
0000000 0d 0a 0a
0000003
$ echo '\r\n' | od -tx1
0000000 0d 0a 0a
