fix a typo from commit a479f0d083 

Yet another gnarly reason to start checking all arg metadata in
linux/pack.subx or something like that. With this bug most of my
programs (including browser-slack!) were working even though the
instruction stream was almost certainly misdecoded halfway through every
attempt to draw glyphs.
