I've no objection to this, but feel it's worth pointing out that for ignoring files like this system-wide, that are not really project-specific, you can add them to ~/.config/git/ignore. For example on my system:

tony@pi:~ $ cat .config/git/ignore
*.out
*.out[0-9]
*.out[0-9][0-9]
*.log
.vimrc
.gdbinit

Learned something very useful today, thanks :)

As recommended by @softins I'll use the local version and close this.

Yep, I wasn't aware of that either!
