This is a very valid point, and given Stefan's argument that these 
version control systems don't have such concepts, I am somewhat 
dismayed. The concept of a root directory of a project is extremely 
useful for things like recursive grep, tags, etc. I find it quite 
helpful to set the default-directory to the vc root in such circumstances.

Oh well, given the arguments, I vote that this is a misfeature and 
should be removed.
