I understand why "." and ".." links can't or at least should not be 
removed. And maybe it would be also inconsistent behavior to follow 
these links and to remove the original target directory.

But I don't understand why "rm -rf ." does not delete at least all 
content within ".".

My use case would be to cleanup "build" directories to start freshly 
like this:

$ pwd
/home/rudi/devel/coreutils/=build-1234
$ rm -rf .
$ ../configure

IMO all workarounds to cleanup "." (inclusive dot-files) are just 
annoying.
