2.3.2 text_area_tag doesn't sanitize the id attribute

Hello,

Rails version 2.3.2 have a bug on text_area_tag which doesn't sanitize the id attribute. See:

text_area_tag('contact[message]', '', :size => '45x15')

The id attribute should be "contact_message", but the Rails isn't sanitizing it... Well, that is setted to 'contact[message]' literal.

The patch is in form_tag_helper.rb, line 260, change from:

content_tag :textarea, content, { "name" => name, "id" => name }.update(options.stringify_keys)

to

content_tag :textarea, content, { "name" => name, "id" => sanitize_to_id(name) }.update(options.stringify_keys)

Thank you
