Can't insert an element before or after an identical element

[Leonard Richardson]

This works in 4.6.3 but not in 4.7.0 (reported by Alex Krupp):

--

text = '<br>'
soup = BeautifulSoup(text, "lxml")

for br_tag in soup.find_all('br'):
  br_tag.insert_before(soup.new_tag('br'))

--

Isaac's comment:

The self check is definitely a bug. insert_before and insert_after can now take multiple arguments, and in the original proposal, we looped through the arguments checking if the tag to be inserted **is** self, the check was moved out of the loop (which makes sense) so we could do the check once, but it is now checking if self is **in** args which is doing check of **equality**, which we do not want to do.

Fixed in revision 495.

Oh, cool. I just created a branch. Didn't realize you fixed it.
