Why shouldn't diesel fuel be stored for long periods of time?

Some time ago you warned against storing a spare can of diesel for too long. Now I have a diesel car I would appreciate a repeat of that advice.

You can find globules of emulsified fuel and condensation appearing in it, particularly the bioethanol element of biodiesel, which is hygroscopic.
