To see what I mean you can type `C-h i d C-u M-x occur RET emacs RET'
and to move the mouse cursor on menu items in occur context lines.
Mouse highlighting is misleading here, because pressing mouse-1 or
mouse-2 doesn't work.  I proposed to remove mouse highlighting on
copied text.

`remove-yank-excluded-properties' is surely related to this, but
I think it is a different thing.  It defines text properties to
remove when yanking, but displaying copied lines in the occur buffer
is not quite yanking.  For example, I customized `yank-excluded-properties'
to t in .emacs, because I want to remove all text properties on yanked text,
but using the same value of `yank-excluded-properties' to remove
all text properties in the occur buffer seems as unexpected and unrelated
thing to me.  Maybe, there should be a separate variable defining a list
of text properties to remove on copied text in the occur buffer.
Do you think it would be useful?
