wrong output of command /usr/bin/seq

[apromix]

The command seq return wrong output when parameter -s is used

$ seq --help
...
-s, --separator=STRING use STRING to separate numbers (default: \n)
...

Example:

On Ubuntu (wrong):
$ /usr/bin/seq -s , 10
1
2,3,4,5,6,7,8,9,10,

On Debian (all right):
$ /usr/bin/seq -s , 10
1,2,3,4,5,6,7,8,9,10

Upstream bug (marked "Done") shows this is a bug in coreutils 8.20: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13227

Since the affected version of coreutils is no longer in a supported release of Ubuntu, I'm marking this bug as Fix Released.

Thanks!
