I got nothing spectacular from that, but changing the \x00s to QRS
gave me something interesting: without the loop, readrune gives me
[?]S, but with it it, it gives me [?]QRS, like cat would've.
Would this be because fullrune doesn't check for validity, and if
chartorune fails then the possibility of eating too much comes about?

Hello. I was looking at the code for the Bgetrune function trying to
implement a readrune() around read(). It works, but without a
counterpart for this:
while(i > bp->runesize) {
Bungetc(bp);
i--;
}
What is the point of that loop? Thanks.
Use "\xE0\x00\x00" as your input and you will find out.
