But it would match what /bin/printf does, and nobody complained about that
being not terribly useful when it was standardized in POSIX.

eval() takes a second argument - if you are computing a value, it is just
as easy to compute it in octal or hex to begin with.  For example,
format(`%b', `\0'eval(computation, `8'))
