Are the generated C files perfectly identical? If you use Cython to
compile the same file twice, will you always get a byte-for-byte
identical file? If so, it should be safe to check them in, and then
have a "make regenerate" that wipes out all Cython-generated files and
rebuilds them. That followed by "git status" would immediately tell
you if something failed to get checked in.
