That is my configuration:
claus-kleins-macbook-pro:cmake clausklein$ git remote -v
master	git://cmake.org/cmake.git (fetch)
master	git://cmake.org/cmake.git (push)

claus-kleins-macbook-pro:cmake clausklein$ git fetch
fatal: No remote repository specified.  Please, specify either a URL  
or a
remote name from which new revisions should be fetched.

claus-kleins-macbook-pro:cmake clausklein$ git fetch master -v
 From git://cmake.org/cmake
