Add a /N switch to the history command

[Gregg Young]

/N would add the item to the history list only if it not already there.

As a bit of a workaround, in my XWP Shutdown folder, I have an object which does this:

4OS2.EXE /c "history | perl -ne '/;/ or print unless $seen{$_}++' > C:\HOME\DEFAULT\.history && delay"

This filters out those lines where I've mistakenly hit ";" instead of ":" (I should improve that to limit those to only those lines containing one letter before the semicolon, I 'spose) and non-unique lines. Thus, multiple occurrences of dir, cd, etc. get filtered when saving the history for re-reading at next startup.

This is no substitute for not cluttering up the list with the dupes in the first place, of course, so your RFE would be quite useful, Gregg.

This is intended to check for dups when using /a. Consider changing /a to do this.

Rev 38287, 38309 HistNoDups=yes in INI makes /a add the item to the history list only if it not already there.
