This is as proper as deleting text from a GtkText widget gets. I
think the widget reuses the memory allocated to the current buffer
rather than freeing it and reallocating it later.

Well, there's the macro GTK_TEXT_INDEX(t, index) for getting the
character at position 'index'. Other than that, I think you can use
gtk_editable_get_chars to get a block of characters.
