 day.

 This is ruining my day, see #10428.

 Replying to [comment:5 goldfire]:
 > Quite possible. I guess I didn't test in 7.10. And, in any case, you've
 simply decided that it's not convenient to merge the change. :)

 So what's the status of this fix? It appears that the example in this
 ticket may be moot, but apparently the fix affects #10428, which *is*
 present in 7.10.1. Did the patch make 7.10.2?
