dactyl_build command or template changed?

When I ran `dactyl_build -S` as described in the README, I found other files with differences besides the edited ones.
Like this (3f510c2).

I'm not sure if the command has been updated or if the template has changed, but I think something needs to be done about it.

Version of the command executed
```sh
$ python -V
Python 3.8.1

$ dactyl_build -v
Dactyl version 0.12.0
```
