Hello Paul,

    Just thought of informing you.
I could not find  '--debug' option in the sort help.
Sort could not even recognize the option.

Currently I am using the following version of sort.
Kindly inform if a latest version is available.

0 $ sort --version
sort (GNU coreutils) 8.5

0 $ sort --debug
sort: unrecognized option '--debug'
Try `sort --help' for more information.

Regards,
Krishna

"sort --help" explains your problem, I expect:

 *** WARNING ***
 The locale specified by the environment affects sort order.
 Set LC_ALL=C to get the traditional sort order that uses
 native byte values.

Hmm, perhaps we should change the output of "sort --help"?
We could change this:

 Report sort bugs to bug-coreutils@gnu.org

to this:

 Please use the --debug option when reporting bugs.
