There are three symbols, 'U', '-', and '+'. From the documentation [1],
they mean:
Each SHA-1 will possibly be prefixed with `-` if the submodule is not
initialized, `+` if the currently checked out submodule commit does not
match the SHA-1 found in the index of the containing repository and `U`
if the submodule has merge conflicts.
