A library function like this should not change global state like
the_index. Granted, read_cache() will not re-read from $GIT_DIR/index
and lose all in-core changes if the index is dirty (i.e. no bad side
effects). But that sort of detail should not be relied on here.
Make the function take the index object from outside instead. The
caller will be responsible for reading index files if necessary.
