Subject: ruby 1.8.0: Error on "%02d" % "08" or "%02d" % "09"

Hi,

I'm using ruby 1.8.0 (Win native and cygwin version). These two commands

	"%02d" % "08"
	"%02d" % "09"

result in the error

	`%': invalid value for Integer: "08" (ArgumentError)

For other numbers/strings (including "8" and "9", but also "01".."07", 
it appears to work as expected -- i.e., as I would expect it.

The problem, I want to solve: Turn strings like "1", "3", "04", "03" 
into a canonical 2-digit string with zeros in front. Should I use a 
different method?

Cheers,
Thomas.
