Yeah... realized I mistyped packed after I sent that.

See attached diff. By the way, if you care about the original code I
used, I snagged it from the much hotter (usually) ff_fill_* methods.
I'm not going to patch those methods because the old code does the
right thing, just not as elegantly.

Yup, it was removing an unused variable (as I documented). New patch
now no longer removes that variable, but also doesn't fix the
incorrect calculation the unused variable does.
