I think that bash do just what we tell it; Since IFS does not normally
contain carriage return, bash treats it as a part of some word;
But then the error message is not very clear, since carriage return is not
visible;

If anyone find it useful, this is a script to print hex dump using
hexdump command:
$ cat /usr/local/bin/hdump
hexdump -f /usr/local/bin/hexdump.fmt "$@"
$ cat /usr/local/bin/hexdump.fmt
"%07.7_Ax\n"
"%07.7_ax " 8/1 "%02x " "-" 8/1 "%02x " " : "
8/1 "%01_p" "-" 8/1 "%01_p" "\n"
Then, for example
$cat /usr/local/bin/hexdump.fmt | hdump
0000000 22 25 30 37 2e 37 5f 41-78 5c 6e 22 0a 22 25 30 :"%07.7_A-x\n"."%0
0000010 37 2e 37 5f 61 78 20 20-22 20 38 2f 31 20 22 25 : 7.7_ax -" 8/1"%
0000020 30 32 78 20 22 20 22 2d-22 20 38 2f 31 20 22 25 : 02x " "--" 8/1"%
0000030 30 32 78 20 22 20 22 20-3a 20 22 0a 38 2f 31 20 : 02x " " -:".8/1
0000040 22 25 30 31 5f 70 22 20-22 2d 22 20 38 2f 31 20 : "%01_p" -"-"8/1
0000050 22 25 30 31 5f 70 22 20-22 5c 6e 22 0a : "%01_p" -"\n".
000005d
It is very useful for me
