Why aren't the character- & hex translation lined up?:

The character is not above the hex value, making it hard to read:

0000000           -   -   -       V   o   l   u   m   e       g   r   o
        20 20 2d 2d 2d 20 56 6f 6c 75 6d 65 20 67 72 6f

It works for me.  When I run this shell script:

echo '      appl' | od -cx

the output is lined up, about as well as it can be:

0000000                           a   p   p   l  \n
           2020    2020    2020    7061    6c70    000a
0000013

If it's not working for you, please supply a test case
like the above.  We can't reproduce the bug simply by
looking at your output.

I don't understand "about as well as it can be". It's either aligned, or it isn't. It's not:

[root <at> alpd054 root]# echo '      appl' | od -ctx1
0000000                           a   p   p   l  \n

But it is aligned, for me.  Most likely you have an old
implementation of od, or an implementation that's not coreutils.

Here's what I get:

$ echo '      appl' | od -ctx1
0000000                           a   p   p   l  \n
         20  20  20  20  20  20  61  70  70  6c  0a

As a side note I notice that solaris and bsd align
to the start of the digits, rather than to the end.
Anyway....

I was able to reproduce this on 5.97:

$ head -n1 /etc/issue
Red Hat Enterprise Linux Server release 5.9 (Tikanga)

$ /usr/bin/od --version | head -n1
od (GNU coreutils) 5.97

$ echo '      appl' | /usr/bin/od -ctx1
0000000                           a   p   p   l  \n
        20 20 20 20 20 20 61 70 70 6c 0a
0000013

Anyway this is already fixed, I suspect by something like:
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commit;h=20c0b870

thanks,
Pádraig.
