I agree with you that it's better to have an extra command. I can work 
around that behavior.

I'm sorry, I'm afraid I don't understand the following sentence:

history -s will not delete the previous history entry before pushing the 
new entry if it's added to a previous entry as part of a compound command.

Thanks for clarifying.

Dennis

This is the result of an interaction between compound or multiline
commands, command-oriented history, and history -s.  history -s
will not delete the previous history entry before pushing the new
entry if it's added to a previous entry as part of a compound
command.  Otherwise, history -s used within a compound command will
remove the entire compound command from the history list.

This seems to be an unusual case; I'm not inclined to change the
current behavior.  Better to have an extra command in the history
than delete them inadvertently.
