Hmm, I had figured they would revert back when they went negative due to damage. This is actually a better interpretation since the loss of CON from the shift could actually lead to the druid's death in the same way barbarian's can die when the rage ends.
The druid player will be happy to hear about my change of interpretation.

It's not an interpretation, it's the literal text in Wild Shape. RAW, directly as printed.
Wild Shape wrote:
This ability functions like the beast shape I spell, except as noted here. The effect lasts for 1 hour per druid level, or until she changes back. Changing form is a standard action and doesn't provoke an attack of opportunity.
Emphasis mine.
So, the druid Wild Shapes, gets knocked unconscious. Since they cannot take the standard action to consciously change back to their natural form, they stay in their Wild Shape until the time period expires or until they wake up and are able to reshift.
