Little shell experiment:

"""
[mike@minobo ~]$ printf '1 2 3 4\n'
1 2 3 4
[mike@minobo ~]$ printf "1 2 3 4\n"
1 2 3 4
[mike@minobo ~]$ printf "1 -2 3 4\n"
1 -2 3 4
[mike@minobo ~]$ printf "1 2 -3 4\n"
1 2 -3 4
[mike@minobo ~]$ printf "-1 2 3 4\n"
bash: printf: -1: invalid option
printf: usage: printf [-v var] format [arguments]
[mike@minobo ~]$ printf "-1 -2 3 4\n"
bash: printf: -1: invalid option
printf: usage: printf [-v var] format [arguments]
[mike@minobo ~]$ printf '-1 2 3 4\n'
bash: printf: -1: invalid option
printf: usage: printf [-v var] format [arguments]
[mike@minobo ~]$ printf ' -1 2 3 4\n'
  -1 2 3 4
"""

Obviously, the printf command is "buggy" somehow, because it should  
not interpret the "-1" in

   printf "-1 2 3 4\n"

as command line parameter.

I will think about filing a bug against Debian's coreutils package.
