Confirmed here. In my test I was getting about 160 milliseconds for last
char, but about 200 milliseconds for char -1. Oddly enough, my items were 4
chars long, and char 4 took about 175 milliseconds.

I also tried the test with much larger strings several hundred k characters
long, and the -1 vs. last delta holds there as well.

I know I sound like a broken record, but I dearly look forward to the day
when I can simply write a language module so that "char -1" transparently
becomes "the last char" behind the scenes.
