Using paths that start with `./` don't seem to work

In some of my scripts I was using `dotnet rimraf ./src/**/bin ./src/**/obj` and they ran, but nothing was being deleted. After switching to `dotnet rimraf src/**/bin src/**/obj` they worked as expected. I assumed prefixing with `./` would work, and swore it did before publishing this, but it's not for some reason.
