Allow Command+H to pass through to OS X (Emacs 23 Nightly)

[Brett Hoerner]

I'm using Emacs nightly Cocoa builds, when I check what is bound to
Command+H I get "A-h is undefined".  I'd like for Emacs to "pass this
through" to OS X like other commands, so that it hides the
application.

Any ideas?

Thanks.
