Ah, you're right, that screenshot clearly has a half-space on the
edges, not a full space.

I'm cool with 'distribute' being the "flush on the edges" behavior -
the current assignation of names is pretty much arbitrary, and if it
matches the text-justify naming, that's cool.

'distribute-space' is acceptable for the half-space-on-edges behavior.
