which previous version of VAX did case insensitive sorting? i never noticed, so i have just tried 1246 in .NET 2003, and it produces this effect. so this change must have happened in an earlier version.
Well I think Valyk made an interesting point. Maybe it comes in handy when a user has two options, one to sort the lines case-sensitive and one to sort the lines case-insensitive? I think they are both usefull; in some situations the one is more usefull as the other. If I have to sort a list lexically (case-insensitive) and there is a case-sensitive ordening (like in Valyk's example), I have to merge the two lists by hand sigh.
