I'm with Craig. Exclude all binaries except that not transformed. Fernandos code works like a spell, no need to store those binaries.

I generate the *.??2 files and the binaries with my tool you find at VFPX. (I dislike binary creation on every checkout / merge / pull. Also it gives an extra layer of security. Also sometimes it's much easier to check old changes against the current version.). There are other posible ways.

To force git to include only usefull files might be a big deal. I've decided to go the other way around. I only include what i like to see in the repo.
Below is an example for .gitignore to include only that.

#note .gitignore works in a the-last-line-wins fashion. So you exclude stuff you have included after it was excluded.
#exclude general (this means nothing included)
