I didn't know this bug had also been connected with commit 72166f.  I
just tried to reproduce it on my master branch, which still has the
commit (I have not yet updated since Martin reverted it), and here are
my results (the indented lines are quotes from the OP):

   When viewing an HTML email using shr, when I left-click on a link, Gnus
   starts 2 browsers and directs each to the URL for the link.

I still see this on master with commit 72166f (in my case it's two tabs
on one browser instance).

   When viewing a plaintext email that contains a URL, when I left-click
   on the URL, Gnus starts a browser for that URL okay, but I also get a
   message like
   
     Buffer is read-only: #<buffer *Article gnu.emacs.gnus*>

I do not see this on master with commit 72166f, but I do see it without
that commit.

   In both cases (HTML, plaintext) middle-clicking on the link/URL works
   okay.

For me too on master with commit 72166f.

In short, the now reverted commit does not completely fix this bug for
me.  And since it introduced bug#23571, which for me is more annoying
than bug#22157, I would prefer it not to be simply recomitted; hopefully
a better fix can be found.
