Rails core - Mar 2006 - Changeset 3953 breaks link_to_remote/AJAX helpers

The change in revision 3953
(http://dev.rubyonrails.org/changeset/3953) seems to have broken some
AJAX helpers for me. In a test view .rhtml file,

  <%= link_to_remote ''blah'',  :url => { :action =>
"test", :param1 =>
''A'',  :param2 => ''B''} %>

produces

  <a href="#" onclick="new
Ajax.Request(''/test/test?param2=B&amp;amp;param1=A'',
{asynchronous:true, evalScripts:true}); return false;">blah</a>

(notice the "&amp;amp;" between parameters, rather than just
"&", or "&amp;")

This HTML escaping is wreaking havoc with the ampersand character used
to seperate parameters, and giving rise to ''amp'' parameters in
the
params Hash. Seeing as this seems to be quite a deliberate change, was
this behaviour expected? Can anyone else reproduce this?

Thanks; checked in a fix in [4014].

There will probably be more double escaping of & issues cropping  
up... I''ll do a search later this evening. If you notice any more  
before then, send me an email and I''ll fix them asap.
