I have no way to reproduce that at will and it has only happened
twice in the last ten years. (Since the first time I make a copy
once in a while.) The second time is several weeks ago.
So, I can say with certainty that when this happened I used vim to
look at the history file in a 80x24 terminal window and that
showed all "^@"s (i.e. 23 lines * 40 nulls = 920 nulls). I'm not
sure whether I looked at any other portion of the file, but
normally I'd check the last line too. I definitely didn't check
what was in between and definitely didn't see anything but nulls.
(The last line may be identical to the first line.)
Ciao
Dominik ^_^ ^_^
