[Tfug] bash history duplication?

[Jerry S.]

if you are doing something like the following:
ls
cd downloads
ls
ls
ls
cd ../mail
ls

your history will look something like:
    68  history
    69  ls
    70  cd downloads/
    71  ls
    72  cd ../mail/
    73  ls
    74  history

Note that the back to back to back ls commands are not repeated in the 
history, but do appear multiple times in the history.  HISTCONTROL only 
stops back to back duplicates.
