builtin-mv: minimum fix to avoid losing files
An incorrect command "git mv subdir /outer/space" threw the
subdirectory to outside of the repository and then noticed that
/outer/space/subdir/ would be outside of the repository. The
error checking is backwards.
This fixes the issue by being careful about use of the return
value of get_pathspec(). Since the implementation already has
handcrafted loop to munge each path on the command line, we use
prefix_path() instead.
