Does true seeing allow folks to identify the druid who is in Wild shape form?

Yes.

Double yes. Especially after the definition I posted on IRC chat yesterday.

To quote it again:

You confer on the subject the ability to see all things as they actually are. The subject sees through normal and magical darkness, notices secret doors hidden by magic, sees the exact locations of creatures or objects under blur or displacement effects, sees invisible creatures or objects normally, sees through illusions, and sees the true form of polymorphed, changed, or transmuted things.
