First off, thanks so much for making this! I use this as well as your bat-extras tools everyday in my development workflow. I'm not sure if this is a bug or a feature request, but figured I would put this out there either way - I couldn't find any similar issues listed atm.

What steps will reproduce the bug?

1. Install bat with sudo apt install bat
2. Create a symlink with: ln -s /usr/bin/batcat ~/.local/bin/bat
3. cd /etc/apt
4. bat sources.list

What happens?
See that you do not get a colored output of the sources.list file

What did you expect to happen instead?
I would expect that since I am able to get syntax highlighting for debsources filetypes in my editor (neovim) that I would also be able to get them with bat

How did you install bat?
