Sourcing bash completion files

[Alarig Le Lay <alarig@xxxxxxxxxxxxx>]

Hi,

I’m currently using the zsh and bash gentoo packages, so version 5.0.5
and 4.3_p42.

I would like to source some bash completion files (for exemple for dig,
I haven’t any completion in zsh).
So, I put this in my ~/.zshrc:
autoload -U compinit promptinit bashcompinit
compinit
promptinit; prompt gentoo
bashcompinit
source /usr/share/bash-completion/bash_completion

But I have an error on the source line:
/usr/share/bash-completion/bash_completion:35: parse error near `]]'

Here is this file: https://paste.swordarmor.fr/yIHW&ln

How can I source this file?

Thanks,
