TextBuffer question

[Benoît Touron <b touron citb bull net>]

Hi !

How can I extract text from a text buffer, and copy it to another 
buffer, and keep the tags of the original text ?
When I use gext_text() on the original TextBuffer (which contains color 
information), then insert a substring of the original text in another 
TextBuffer, the colors are lost.
Any idea ?

Thanks
Ben
