 Ruby:
 {{{
 ruby -e 'puts "%-10s%s" % ["a", "b"]'
 a         b
 }}}

 MacRuby SVN r3441:
 {{{
 macruby -e 'puts "%-10s%s" % ["a", "b"]'
 ab
 }}}

 This happens because `sprintf.cpp:rb_str_format:467` transforms `%s` into
 `%@`, and asks for formating to `CFStringCreateWithFormat()`, which does
 not handle the "field width" flag for Cocoa objects (`%@`).

 A possible fix might be to explicitly call `-[NSObject description]` and
 then get the UTF8/16 C string (which means `%s` would not be transformed
 into `%@`), but I'm not sure this is a pretty fix :D
