ri busted for some core classes

[Phrogz]

After upgrading to 1.8.4 using one-click, ri isn't working for some
items:

C:\Documents and Settings\gavin.kistner>ri Array
C:/ruby/lib/ruby/1.8/rdoc/ri/ri_descriptions.rb:99:in `concat': can't
convert nil into Array (TypeError)
from C:/ruby/lib/ruby/1.8/rdoc/ri/ri_descriptions.rb:99:in
`merge_in'
from C:/ruby/lib/ruby/1.8/rdoc/ri/ri_reader.rb:56:in

C:\Documents and Settings\gavin.kistner>ri Array#concat
-----------------------------------------------------------
Array#concat
array.concat(other_array) -> array
------------------------------------------------------------------------
Appends the elements in other_array to _self_.

[ "a", "b" ].concat( ["c", "d"] ) #=> [ "a", "b", "c", "d" ]

C:\Documents and Settings\gavin.kistner>ri --version
ri v1.0.1 - 20041108

C:\Documents and Settings\gavin.kistner>ruby --version
ruby 1.8.4 (2006-04-14) [i386-mswin32]

I found two other references to this in the nntp archive, but no
followup responses. Using fxri for Array or String causes fxri to crash
(unsurprisingly).

I tried regenerating my system-wide ri data, to no avail:

C:\ruby\src\ruby-1.8.4>rdoc -R

Anyone got any groovier suggestions?

....and then I searched some more and found the answer.[1] Thanks to
oinkoink for posting it. Can someone please get this patch into the
one-click installer so that Ruby doesn't look broken out of the box
when I convince all my friends to install it?

I mean, our state of documentation is one common sore point (though
getting better); to have the documentation totally broken for a couple
really core classes is especially bad.

This was already fixed in CVS.
