Bug in String#rjust

Matt Mower

Hi.

I'm using one-click-installer Ruby 1.8.2 (2004-11-06) on WinXP-SP1 and
I think I have a bug in the String method #rjust

irb(main):002:0> "0".rjust( 2, "-" )
=> " 0"
irb(main):003:0> "0".rjust( 2, "-", 22 )
ArgumentError: wrong number of arguments (3 for 2)
from (irb):3:in `rjust'
from (irb):3
irb(main):004:0>

It's expecting 2 parameters, but ignoring the padding argument and using spaces.

Does anyone else see this?

Works for me:

13:56:07 [source]: irbs
>> "0".rjust( 2 )
=> " 0"
>> "0".rjust( 2, "-")
=> "-0"
>> RUBY_VERSION
=> "1.8.1"
>> exit
14:17:53 [source]: uname -a
CYGWIN_NT-5.0 bond 1.5.12(0.116/4/2) 2004-11-10 08:34 i686 unknown unknown
Cygwin

Kind regards
