Adding a default .gitignore for new R projects is a nice features. Around 20% of CRAN packages contained compiled code, often C/C++ (and increasingly Rust etc). Those packages will when git add everything is used also commit their object code and shared libraries. With this PR they will no longer so it should offer a small quality-of-life improvement to these repositories.
