In this case, I can remove it from both cases. It is not right to 
maintain two lists and have one which is different from the other for no 
reason. We can do what you prefer, but in sync.

I am uneasy with the idea of removing stuff in the whole history because 
it was used again. Maybe just because I am use dthe the 'ignoredups' 
history control of bash, instead of 'erasedups'.

Moreover, the justification in your first message was only for the last 
command, not for the older ones. But I am open for arguments on when it 
is useful.
