how to disabling cut&paste of tags in GtkTextBuffer

[Olivier Sessink <olivier lx student wau nl>]

Hi all,

the default behaviour of the GtkTextBuffer is to copy/paste tags
(GtkTextTag) along with the text. My application depends quite a bit on
the exact position of the tags, so tags inserted by copy/paste are quite
often not on the right place.

So my question is: is there a way to make the GtkTextBuffer copy/paste
only the text and not the tags that are in the text?
