Add option to `git add` with `--force`

[bryant1410]

Hey, I use this tool to publish a compiled PDF, however PDFs are ignored by a global gitignore file.

So it seems it creates a commit without this file, as I believe the git add is failing because it'd output something like:

The following paths are ignored by one of your .gitignore files:
[FILE]
Use -f if you really want to add them.

Can you add an option that does git add -f (or --force)?
