For example, in dom/base/nsGkAtomList.h, we currently have:
GK_ATOM(mouseWheel, "mouseWheel") // For discrete wheel events (e.g. not OSX magic mouse)
but if we change to
GK_ATOM(mouseWheel,
"mouseWheel") // For discrete wheel events (e.g. not OSX magic mouse)
The parser didn't handle the declaration
It's a sub-class of nsAtom, useful for cases where you know you are dealing
exclusively with static atoms. The nice thing about it is that you can use
raw nsStaticAtom pointers instead of RefPtr<>. (In fact, the AddRef/Release
implementations ensure that we'll crash if we use RefPtr<nsStaticAtom>.)
