bat breaks zsh-async

[pointlessone]

What steps will reproduce the bug?

1. Use zsh with zsh-async prompt (Pure or Spaceship, for example)
2. alias cat=bat
3. Start a new shell

What happens?

zsh-async doesn't work. It seem to start the process (there's a bat child process) but the prompt never update the async parts.

What did you expect to happen instead?

I expected bat to be a drop-in replacement for cat and not break my shell prompt.

How did you install bat?

homebrew

Please see mafredri/zsh-async#44 and the referenced fix therein. Do you have a version of zsh-async with that fix? Or maybe this is broken again?

[sharkdp]

Would still be interesting to know why bat as a cat replacement doesn't work in that scenario. Maybe someone could use strace to track down the exact cat/bat call and see which arguments are being passed.
