zsh autocompletion not quite right for "sccs delget"

[Sebastien Roy <sebastien.roy@oracle.com>]

Hi folks,

I'm running zsh 4.3.10, and the "sccs delget <file>" command doesn't do 
autocompletion on the file argument.  This is in contrast with other 
sccs subcommands (e.g. diffs, create, etc.), which correctly do this.

It appears that there's a files argument missing from the delget entry 
in the Completion/Unix/_sccs completion file:

   sact|print) _sccs_files;;
   create|enter) _files;;
   deledit|delget|delta)
     _arguments '-s[silent]' '-y+[specify delta commentary]:comment'
   ;;
   diffs)
     _diff_options diff "$sfiles" "$ropt" "$copt" \
       '-C[output a context diff]'
   ;;
