I think it's just generally good practice to quote variables because
they could have spaces in them. However, in the case of the -eq
operation, anything other than a single integer with no spaces will
produce an error anyway.
I think it's just a good habit to be in, to quote variables, even if the
specific instance doesn't actually call for it.
