[O] [BUG] Unable to use TODO(address@hidden) to track TODO state changes

[Jason Dunsmore]

After reading http://orgmode.org/org.html#Tracking-TODO-state-changes, I
expected the "@!" TODO syntax, eg. TODO(address@hidden), to do the following:

- Log timestamp when entering state
- Add note when entering state

This syntax appears to break the functionality, because it does neither.
The state is changed with no logging or note prompt.  Is this a bug?

I verified that the TODO(t@/!) syntax does work as indicated in the
manual.

- Add note when entering state
- Log timestamp when entering state
- Log timestamp when exiting state

This is with the latest org-mode (commit a4273cbe0e0) and Emacs 23.2.1.

Thanks,
Jason
