Good point. As far as my research goes, this flag was introduced in Nov. 2001: http://core.tcl.tk/tk/info/5265df93d207cec0 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: http://core.tcl.tk/tk/info/549d2f56757408f3 Markus -- - - - - - - - - - - - - - - - - - - - Dipl.
