When your program does something that could result in changing the text, it
will usually be obvious whether something will change, e.g., an insert/paste
(empty selection) or a delete (with non-empty selection).

The only case that's slightly complicated is an insert (or paste) with a
non-empty selection, when you need to check if the current selection = what's
being inserted.

Seems simple - am I missing something?
