wishlist: sort -v, --version-sort like ls -v, --sort=version

[Bob Proulx]

The 'ls' command has a very useful sort function 'ls --sort=version'.
Recently I was needing to sort a file using that same method.  It was
a file of filenames.  But the 'sort' command does not implement this
functionality at this time.

I contemplated touching the entire list to create files of those names
in a temporary directory and using ls to print the list in version
sorted order.

It would be reall great if sort also implemented the version sort
functionality.

Thanks
