@jakaskerl could you please review & merge this?

Maybe add .env as well. Is there an instance where it would not be best if we ignored all . (dot) files anyway?

IMHO this quite depends on the project. I've seen people using .env as a default config and just ignoring .envrc. In general, I wanted to kick this off and leave specifics for later (but I'm open to suggestions / including more entries here).

Also, after a discussion with @alesh-kajzar and brief testing, I pushed a commit with (commented out) overrides for paths that are ignored by default (in case someone really wants to include these).
