savecore.c revisited

[utzoo!decvax!pur-ee!purdue!cak]

Ooops, I goofed. In the recently published fix to savecore.c, I forgot
something. It's not good enough to just extend the array size. Here's
the diff that makes the difference:

    *** /usr/src/cmd/savecore.c	Fri Jan 15 11:43:47 1982
    --- /usr/src/cmd/savecore.c.v0	Thu Jan 14 16:40:51 1982
    ***************
    *** 87,93
	    register int dfd = Open("/dev", 0);
	    struct direct dir;
	    struct stat statb;
    ! 	static char devname[DIRSIZ + 6];
	    char *dp;
      
	    strcpy(devname, "/dev/");

    ! 		devname[DIRSIZ + 6] = '\0';
		    if (stat(devname, &statb)) {
			    perror(devname);
			    continue;

			    continue;

Oh the humiliation of incomplete testing!
