*SVN*
+* Added FormHelper#form_for and FormHelper#fields_for that makes it easier to work with forms for single objects also if they don't reside in instance variables [DHH]. Examples:
+
+ <% form_for :person => @person, :url => { :action => "update" } do |f| %>
+ First name: <%= f.text_field :first_name %>
+ Last name : <%= f.text_field :last_name %>
+ Biography : <%= f.text_area :biography %>
+ Admin? : <%= f.check_box :admin %>
+ <% end %>
+
+ <% form_for :person => @person, :url => { :action => "update" } do |person_form| %>
+ First name: <%= person_form.text_field :first_name %>
+ Last name : <%= person_form.text_field :last_name %>
+
+ <% fields_for :permission => @person.permission do |permission_fields| %>
+ Admin? : <%= permission_fields.check_box :admin %>
+ <% end %>
+ <% end %>
+
* options_for_select allows any objects which respond_to? :first and :last rather than restricting to Array and Range. #2824 [Jacob Robbins <jrobbins@cmj.com>, Jeremy Kemper]
* The auto_link text helper accepts an optional block to format the link text for each url and email address. Example: auto_link(post.body) { |text| truncate(text, 10) } [Jeremy Kemper]

module FormHelper
+ # Creates a form and a scope around a specific model object, which is then used as a base for questioning about
+ # values for the fields. Examples:
+ #
+ # <% form_for :person => @person, :url => { :action => "update" } do |f| %>
+ # First name: <%= f.text_field :first_name %>
+ # Last name : <%= f.text_field :last_name %>
+ # Biography : <%= f.text_area :biography %>
+ # Admin? : <%= f.check_box :admin %>
+ # <% end %>
+ #
+ # Worth noting is that the form_for tag is called in a ERb evaluation block, not a ERb output block. So that's <tt><% %></tt>,
+ # not <tt><%= %></tt>. Also worth noting is that the form_for yields a form_builder object, in this example as f, which emulates
+ # the API for the stand-alone FormHelper methods, but without the object name. So instead of <tt>text_field :person, :name</tt>,
+ # you get away with <tt>f.text_field :name</tt>.
+ #
+ # That in itself is a modest increase in comfort. The big news is that form_for allows us to more easily escape the instance
+ # variable convention, so while the stand-alone approach would require <tt>text_field :person, :name, :object => person</tt>
+ # to work with local variables instead of instance ones, the form_for calls remain the same. You simply declare once with
+ # <tt>:person => person</tt> and all subsequent field calls save <tt>:person</tt> and <tt>:object => person</tt>.
+ #
+ # Also note that form_for doesn't create an exclusive scope. It's still possible to use both the stand-alone FormHelper methods
+ # and methods from FormTagHelper. Example:
+ #
+ # <% form_for :person => @person, :url => { :action => "update" } do |f| %>
+ # First name: <%= f.text_field :first_name %>
+ # Last name : <%= f.text_field :last_name %>
+ # Biography : <%= text_area :person, :biography %>
+ # Admin? : <%= check_box_tag "person[admin]", @person.company.admin? %>
