Side note: the "pretty" way to do this is using "'#' in the format, ie "%#lx".

It doesn't do that "if (argc < 10)" special casing thing you do - but
it *does* treat 0 specially (so it prints out just 0, not 0x0)

Admittedly we clearly don't typically do that pretty thing, with

        git grep '0x%' | wc -l ; git grep '%#' | wc -l

resulting in

        40012
        5237

respectively.
