Description of problem:
The --version-sort (-V) option of sort(1) is not honored in multibyte
locales.

Version-Release number of selected component (if applicable):
coreutils-7.2-1.fc11

How reproducible:
100%

Steps to Reproduce:
1. { echo "narf.9"; echo "narf.10"; } | sort --version-sort
  
Actual results (just a lexical sort):
narf.10
narf.9

Expected results (sorted ala 'ls -v'):
narf.9
narf.10

Additional info:
Detection of key->version was apparently inadvertently omitted
from keycompare_mb() (it is in keycompare_uni() ).
Fix is simply to clone it from the latter:
