i'm not sure "use all 80 columns" is actually a goal :-)

the current code definitely looks good on a medium-sized machine:

  Mem:    63978M total,    55294M used,     8684M free,     1889M buffers
 Swap:    56095M total,        7M used,    56088M free,    37331M cached

ironically it's less readable on low and mid-range phones, here a mid-range
4GiB device:

  Mem:  4024836K total,  3976272K used,    48564K free,     4276K buffers
 Swap:  3018620K total,        0K used,  3018620K free,  3258468K cached

personally i'd have gone with 1GiB rather than 10GiB so you get at most 6
digits rather than 7 --- i guess i'm just below average and you're above[1]
:-)

time and Moore's law will solve this anyway, given that the largest phones
already have 12GiB! (although laptops for real people seem to have stalled
at 8GiB, so maybe that will happen with phones too.)
