Both are 'fake' WGL extensions. I agree that no string should be displayed in either case and that we don't need a check for NV_texture_rectangle.
The loading of the NV vertex array range stuff depending on the presence of the GL extension of which it is part is fine. Yes, GL extensions are context dependend but relying on glXGetProcAddress is even more evil (as it doesn't have to return NULL). Upto now I haven't seen problems with this.

This patch and the next are designed to remove the need for context-specific information taken from a temporary context. For this one, the aforementioned extensions don't have WGL extension names. Their respective specs and a recent nvidia card/driver's WGL extension output confirms this.
