Add fold markers to a .c file

Fold markers can make it easier to navigate source code. Add them to this .c file.

Start file
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#include <assert.h>

void copy(char *to, char *from, size_t count) {
    register n=(count+7)/8;
    switch(count%8){

    case 6:         *to = *from++;

    case 3:         *to = *from++;
    case 2:         *to = *from++;
    case 1:         *to = *from++;
            }while(--n>0);
    }
}
