By default .Rproj.user files are added to .gitignore, but why not *.Rproj?
I wonder if .Rproj files should also be added to the .gitignore file.
When a project is newly created, the file is rather small (~ 234 Bytes) so it shouldn't really matter with respect to size.
Are there other files that should be added to gitignore by default? Maybe *.zip files?
