We already do so in the native execution case, and a few descriptions (I
did notice this with SHA ones) are short enough for the output to look
slightly odd.

Many descriptions are longer than 37 characters, so I wonder whether we
wouldn't want to bump the padding to 50, 60, or even 70. And this
perhaps despite then going out of sync with the individual insn tests
earlier on (which I wouldn't want to touch).

back by Thursday (i.e. including the Community Call as an option to voice
