Add the options `:dir` and `:base` to the %(refname) atom. The `:dir`
option gives the directory (the part after $GIT_DIR/) of the ref without
the refname. The `:base` option gives the base directory of the given
ref (i.e. the directory following $GIT_DIR/refs/).
Add tests and documentation for the same.
