commandline includes redirects without their < or >, regardless of --tokens-raw or any other tokenization scheme in fish 4.0b1. The same holds true for the different tokenization in 3.7.1. e.g., for:

command <in >out

commandline --tokens-raw outputs:

command
in
out

When it should output:

command
<in
>out

Otherwise, you cannot distinguish between <in, >in & in.
