/**
* Binary coded decimal support.
*
* <p>This allows linker scripts to generate dd commands. Leading spaces
* need to be inserted so Mac doesn't consider them octal; therefore,
* parameters must be quoted; and eight digits should be good enough.
* <p>This allows linker scripts to generate dd commands, e.g. ape.lds.
* There are a few ways to pad each number to the necessary 8 bytes.
* Spaces cannot be prepended because busybox refuses to parse them.
* Zeros cannot be prepended because Mac will take numbers as octal.
* That leaves appending spaces. The user's shell ought to treat any
* unquoted run of spaces as if there was only one, so this is safe.
