Doesn't that remove the special meaning of "\x" which states that what follows is a hex code ?

Code:
$
$ printf "abc\x0Ddef" | od -bc
0000000 141 142 143 015 144 145 146
          a   b   c  \r   d   e   f
0000007
$
$ # sed
$ printf "abc\x0Ddef" | sed 's/\\x0D/\\x0D\\x0A/g' | od -bc
0000000 141 142 143 015 144 145 146
          a   b   c  \r   d   e   f
0000007
$
$ # perl
$ printf "abc\x0Ddef" | perl -ne 's/\x0D/\x0D\x0A/g; print' | od -bc
0000000 141 142 143 015 012 144 145 146
