Ticket #3 (defect)

On some shells, printf is built in, and has different syntax rules than the system printf command. For example,

sh-3.1$ printf "---- now is the -- time\n"
sh: printf: --: invalid option
printf: usage: printf [-v var] format [arguments]
sh-3.1$ /usr/bin/printf "---- now is the -- time\n"
---- now is the -- time

We fixed the problem here by using echo instead of printf, but I think two leading dashes will do the trick as well?
