pulling grub from core-testing

Hello everbody, grub 2:2.06.r557.gac560966d-1 was reported to be bad... Looks like it results in stalled boot and black screen (on some systems). No idea what caused this for now. Pulling from core-testing so it can not cause more harm... -- main(a){char*c=/* Schoene Gruesse */"B?IJj;MEH" "CX:;",b;for(a/* Best regards my address: */=0;b=c[a++];) putchar(b-1/(/* Chris cc -ox -xc - && ./x */b/42*2-3)*42);}
