git-mv: shrink usage, no usage on error

Browse Source 
Small fixes to be consistent with other git scripts:
- usage message is only about options and arguments
- on error, exit(1) without the usage message

Additionally, "beautifies" output with -n a little bit

symlink or directory, dest must not exist. It renames source to dest.
In the second form, the last argument has to be an existing
directory; the given sources will be moved into this directory.
Updates the git cache to reflect the change.
Use "git commit" to make the change permanently.
