Doh. Please try to communicate what you're working on. I was just about to hit
SEND on a series to fix the truncation bug, and to add a similar test. I would
have happily punted that in your direction, but I had no idea that you were aware
of the bug[*], let alone working on a fix. I could have explicitly stated that
I was going to fix the bug, but I thought that it was implied that I needed to
clean up my own mess.

Anyways, I'm going to hit SEND anyways, my changes are slightly different to your
patch 1 (truncate needs to happen between begin() and end()) and patch 3 (I added
a slightly more comprehensive test).
