fortune(1) should keep using the format it always has. There's no reason to change it, we have files written for it, and it keeps interoperability with other implementations.

We have a character set specifically catered to use in this context. We
have the luxury of not having to worry about breaking compatibility
because we are a cohesive system and there is a native tabular format
that is specifically designed to circumvent weirdness like using a
percent sign as a tabular character.

As a note, 9front’s fortune(1) implementation seems to work differently
to how Unix fortune(1) does. It has no percent characters as far as I
can see.

prints a one-line aphorism chosen at random.

I was correct.

9front's format is the same as the historical implementation; if I recall correctly the first implementation used a 500B buffer and looped fgets(3) randomly. The percent delimiter might have been a BSD invention. It's nice to be able to see the sources for quotes without bad line-wrapping.

We don't exist in a vacuum. There already exists two fortune file formats. I don't want to invent a third.

weirdness like using a percent sign as a tabular character

ed(1) used \n.\n to cease input. \n%\n fits with that pattern. It's not like % as a single fortune is useful.
