\map v $ma81a ^[81^V|D`alld0:s/  / /g^M$p^M

A nice map, but it has a small bug: try to center a line that's been centered
already, or any line with indentation.  Furthermore, after applying the macro
every line ends in a space!
Let's try again:

	map v :s/^[ ^I]*//^V^M$ma81a ^V^[81^V^V|D`alxd0:s/  / /g^V^M$p^V^M
