Hi,

I am unsure whether or not this a bug. Anyhow, it is pretty annoying...

I use simple multi-line scripts very often in bash and use vi mode to edit them. By using
# shopt -s cmdhist
# shopt -s lithist
I can achive multi-line editing. Which is fine.

But this ability "breaks" as soon as I close bash and open it again.

Is this a bug?
Are there suggestions for workarounds?

Thanks and with best regards,
Slevin

DETAILS / HOW TO REPRODUCE

the bash I use
# bash --version
GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin10.0)
Copyright (C) 2007 Free Software Foundation, Inc.


an example multiline script
# for i in 1 2
> do
> echo $i
> done
1
2


let's look into the history. Looks good, command #409 is my multiline script
# history | tail -n 10
echo $i
done
  406  history | tail -n 5
  407  history | tail -n 10
  408  bash --version
  409  for i in 1 2
do
echo $i
done
  410  history | tail -n 10



I can easily repeat #409. I can also go back in the history and vi the whole script
# !409
for i in 1 2
do
echo $i
done
1
2



Exit the shell and start it again
# exit



Look at the history again
# history | tail -n 10
  417  history | tail -n 10
  418  for i in 1 2
  419  do
  420  echo $i
  421  done
  422  exit
  423  exit
  424  history -n 10
  425  history | tail -n 15
  426  history | tail -n 10


Shit. The multiline script has been saved as more then one command
Re-executing the script or vi'ing the script ain't possible...
# !418
for i in 1 2
