Funny, I was saying the same thing to someone privately a few days ago.
That would be the same person who likes to poke fun at my written
vernacular, which occasionally contains such phrases as "there y' go"! :-)
Shucks ma'am, I cain't talk any different 'n I know!
BTW, an a priori approach to the text itself goes a long way in eliminating
such ideas as "verbose cipher", "cipher pairs", etc. These ideas rely on
concepts of text compression or expansion, and spaces being arbitrary, where
the evidence, both a priori and mathematical, suggests that the spaces are
more often than not in their proper place and the text is consistent and of
normal length.
