git cole give unexpected error message

Encountered following minor issue today:

Executed: sam@mars ~/work $ git clone git://git.kernel.org/pub/scm/lib/klibc/klibc.git viggo defaulting to local storage area fatal: unexpected EOF

The errormessage "fatal: unexpected EOF" did not immediately tell me that the requested git repository did not exists.

But I corrected the path and tried again: sam@mars ~/work $ git clone git://git.kernel.org/pub/scm/libs/klibc/klibc.git viggo viggo already exists.

So one can see that git did not clean up after the faulty clone.

It would be nice if git:
1) Displayed a more meaningfull error message
2) Cleaned up so I did not have to do a manual rm -rf viggo

cogito being a nice porcelain gives the git errormessage but manage to clean up when the clone fails. So also cogito would benefit from a more descriptive errormessage.
