random() on an empty table raises instead of returning None#73

Conversation

The docstring promisesNone; anything below 1 now returns it.Split out of #60 (one PR per issue). This branch carries only this issue's fix and its tests; the rest of the known-bug inventory stays
xfailed, so the full suite is green here and the strict markers guarantee no cross-issue leakage.
