I tried to report this as a bug via the website but I'm being flagged as spam, even when logged in. (Meta bug?)
Anyway:
If I double-click on the && in the following line of text:
if( transform.position.z > CameraTransitionAltitude && !AboveCamera.active ){
I select " && !" which is definitely not what I want or expect.
I've had similar oddness with double-click selection elsewhere but this set me off.
