Sorry for the delay, trying to get to at least one toybox thing a day...

free: looks good.  Cleanups: printf->xprintf(), swapping spaces for tabs
(and bigger printf padding constants) to save a couple bytes.

This is a fairly idiosyncratic command, is there a spec for it anywhere?
 (Not susv4...)  The gnu/dammit version seems to default to kilobytes
instead of bytes, but doesn't have any indicator of this in the output...

(I'm actually slightly torn over the xprintf() because the other
versions don't exit with an error when you do "free > /dev/full"... but
I think they probably _should_...)

P.S. I say "gnu/dammit" because the FSF guys keep insisting "It's
gnu/linux/dammit", so I'm guessing both halves of the bracket are part
of the full name when they're referring to the Linux versions of their
software.  At a guess, "gnu/solaris/dammit" is the name of their Indiana
binaries, and "gnu/macosx/dammit" for the ports to that platform...

P.P.S. Well, maybe a _little_ bitter.
