bug#22319: 25.1.50; Emacs hangs when pasting in xml file (+ flyspell-mode)

[Jan Synacek]

Steps to reproduce:
1) C-x C-f foo.xml
2) M-x flyspell-mode
3) Then paste in the following:
<?xml version="1.0" encoding="UTF-8"?>
<Simulation>
      <compare>
        <data>fullprint1</data>
      </compare>
      <!-- <compare>
        <data>fullprint2</data>
      </compare> -->
</Simulation>
4) Go to the line with fullprint2:
   C-k C-k
5) Go to the line after fullprint1:
   C-y
   At this point, emacs hangs, eating all of my CPU.

The tested version is the current upstream master (commit 61e83e9).
