[split] Line padding, layout, Currier's "groups of letters"...

[nickpelling]

I thought it was clear enough that the small group Currier was talking about was EVA am.

I think it says a lot about EVA that removing -m typically produces nonsense words, but removing -am or replacing -am with -ar does not.

I also think we're a long way from providing an account of labelese so comprehensive that it can answer questions about other variants of Voynichese.
