I was fixing this by implementing octal escapes, I just haven't gotten back to
that tab yet. :)

I'm kinda frustrated that we've already implemented \c support twice elsewhere,
and it's not sharing code. :(

$ grep "'c'" toys/*/{echo,printf}.c
toys/posix/echo.c:        else if (slash=='c') return;
toys/posix/printf.c:  if (*ptr == 'c') xexit();
toys/posix/printf.c:        } else if (c == 'c') printf(toybuf, wp[0], wp[1], *aa);

I should take a look at that...

Yay tests,
