Subject: [9fans] Bgetrune while(i>runesize) loop
Topicbox-Message-UUID: e1953bbc-ead3-11e9-9d60-3106f5b1d025

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.
