thanks erik,

some careless misses.

int
checkname(char *s)
{
	int i, n;
-	Rune c;
+	Rune r;

	if(s == nil || *s == 0)
		return Ename;
	if(*s == '.' && (s[1] == 0 || (s[1] == '.' && s[2] == 0)))
		return Edot;
	for(i = 0;; i += n) {
-		n = chartorune(&r, s);
+		n = chartorune(&r, &s[i]);
		if(i+n >= NAMELEN)
			return Etoolong;
		if(r == 0)
			return 0;
		if(n == 1 && r == Runeerror)
			return Ename;
-		if(r <= 040 || r == 0x7f)
+		if(r < 040 || r == 0x7f)
			return Ename;
	}
}
