[split] Diplomatic ciphers

[Mark Knowles]

JKP: My slight acquaintance with what you term janus pairs or common biglyphs in addition to the repeated words, which I can only really understand as being nulls, was one reason I thought about what we are calling here block or multiglyphs. As well as of course the fact that introducing this verbosity factor could then lead it to fit more closely with a diplomatic style cipher.
