reading [y] as a null character

[Koen G]

Nulls are often mentioned when it comes to possibilities we can expect, so it is on my "to check" list. However, the verbose cipher thing took me so long that I moved on to imagery for a while. 

What I was planning was to check what would happen for each glyph if it was treated as a null. And combinations of glyphs, like what if [a, o and y] are all nulls? I don't understand why [y] should be a special case though. Take [a] for example; instead of merging it with each possible combination of following glyphs, it may be simpler to just omit it.
