        I could, but my configuration files total over 5000 lines in 24
files, so I'd rather not if I can avoid it :) Especially since I
prefer the current behavior to the default one anyway, I just think
it could be even better :)

        I thought about that, especially since I have autocutsel configured
to duplicate the application's copied text to the X buffer (i.e if I
hit "M-w" in (X)Emacs or "C-c" in other applications, then I can
paste with the middle mouse button). However, it only copies in one
direction (i.e if I select with the mouse, this copies the text into
the X buffer but not to the application buffer). I have done the
following tests to confirm:
  - Stop autocutsel -> emacs' behavior is unchanged;
  - Test with emacs -Q -> selecting text with the mouse does not
    affect the copied text;
  - Test with other applications (namely XEmacs, kate and geany)
    -> They all behave the way I want.

        However, you gave me an idea and I did an extra test: going back to
my original scenario, if I select "bar" then click somewhere else
(to empty the selection) and then paste, the pasted text is "bar"
and not "foo". So, is there some setting in *Emacs* that could cause
text selected with the mouse to be automagically copied to the kill
ring and yank buffer?
