When using a prompt with multiple lines the prompts frequently breaks
You can try something like:
typing hello then Ctrl-C

Starting with:
  [multiline prompt]
  $ hello

Then <ctrl-C>:
  [multiline prompt]
  [mhello^Ce prompt]
  $
This happens on other occasions as well like switching from command
mode to insert when using vi-binding.
However, happens even when vi-binding is not set

I tested the same fish version with the same fish configurations (as
far as I can tell) on macos and had no issues.

I am using Debian Bullseye:
  [multiline prompt]
  $ uname -a
Linux mylaptop 5.10.0-1-amd64 #1 SMP Debian 5.10.4-1 (2020-12-31)
x86_64 GNU/Linux

I am using the same version of Fish on debian testing with the standard
prompt "Nim" from `fish_config`
