Good to know, sgosnell, thanks.

BTW, I failed to mention that there are different levels of location precision. You can specify which level apps can access. The lowest precision is from cell tower and wifi information. Next is GPS only, and the highest precision is from assisted GPS, which also includes cell towers and wifi. I tend to keep mine set to the lowest, because it uses the least battery power. With the highest precision set, I can use various online services to track my phone, and see which room in my home it is in. This can occasionally be handy, but really only when I can't find the damned thing easily. Usually I use my wife's phone to call it. With the lowest precision set, I can see that it's somewhere in the neighborhood, within a couple of blocks. The only way to prevent anyone from knowing your location at all is to turn the phone off. Anyone with any authority can access the cell tower data, such as the police. If you make a 911 call on your cellphone, they will try to locate you as accurately as possible, and can easily get a cell tower triangulation, which is of varying accuracy depending on the number of cell towers in the area and their relative positions. If the phone is on, they can track you pretty closely, and this isn't just Android, it also works on flip-phones or anything else, regardless of the OS.

I have no idea how a flashlight asks for that. Since I have no idea, I don't accept it and move on to next app.

There has been speculation before on some of the flashlight apps. Just moving on to something else is probably the most logical policy. My Samsung phone has a flashlight app built in, no need for any third-party apps, and ISTR that Cyanogenmod has it in their ROMs also. One can certainly choose not to install any app that they don't trust.
