Hi,

I manage my own undo buffer of changes made to a gtk.TextView. This 
necessarily means that the undo controller is connected to the relevant 
TextBuffer's "delete-range" and "insert-text" signals. Changes made 
during these signals are stored on the undo stack.

Then I ran into some weird behavior: when I select any region of the 
text in the text buffer and then paste something in that was previously 
copied to the clipboard, an "insert-text" and then a "delete-range" 
signal is emitted. This means that, when undoing, the "delete-range" is 
undone first and this leaves both the originally selected text as well 
as the text it was replaced with in the TextView, until undo is called 
again, undoing the "insert-text" changes.

Is there a signal I can connect to to catch this special case, or does 
anyone have another idea of how to combine these two into a single undo 
step?

Thanks in advance,

Walter
