bug#11355: 24.1.50; Middle click on flyspell-mode fixes a word, but also paste text

[Daniel de Angelis Cordeiro <dcordeiro@gmail.com>]

This is a minor (but annoying) bug.
In order to correct a mispelled word in Flyspell-mode one must click
with the middle-mouse button. Starting with emacs 24, the middle-click
fixes the word but also pastes some text that was copied before. :(
