Are all semi-modern Tcl/Tk in service have this -undo thing so that
we can pass unconditionally to the text widget like the patch does?
Good point. As far as my research goes, this flag was introduced in Nov. 2001:

To defend Gitk developers, the Tk guys apparently change their mind on the default value from time to time. Official documentation says nothing about a default, the proposal from 2001 talks about -undo 0 as default and there are recent commits changing this default:
