Ah, you know I'm trigger-happy :)

The reason I do like to commit experimental patches like this one is
that otherwise I'll never *really* test it.

I think not. They have different use scenarios. I think this is fine.

IMO we should just commit it and get a feel for it. It's not altering

This can be tricky. Although for most formats, the announced
PLAINTEXT_SIZE *is* in characters until you give -enc=utf8 and have
called the formats' init(). So I believe what you announce is pretty
