I don't see this:
z4(1)$ HISTFILE=histfile ./bash
z4(2)$ history
1 history
z4(2)$ echo a
a
z4(2)$ echo b
b
z4(2)$ echo c
c
z4(2)$ exit
exit
z4(1)$ cat histfile
history
echo a
echo b
echo c
exit
z4(1)$ HISTFILE=histfile ./bash
z4(2)$ HISTCONTROL=erasedups
z4(2)$ ls
z4(2)$ ls
z4(2)$ history
1 echo a
2 echo b
3 echo c
4 exit
5 HISTCONTROL=erasedups
6 ls
7 history
z4(2)$ exit
exit
z4(1)$ cat histfile
history
echo a
echo b
echo c
exit
HISTCONTROL=erasedups
ls
history
exit
(I omitted the `ls' output.)
The history file does not contain multiple `ls' commands.
