That's not a bug.  If you insist on printing with a format string that
starts with -, POSIX requires that you use -- to end arguments, as in:

$ printf -- ---%s---\\n test
- ---test---

If your non-builtin system printf behaves differently, that is a bug in
your system printf.

Don't work too hard, make some time for fun as well!
