What's the secret in getting bash to perform like ksh during
command-line substitution?

I've set bash to use vi editing via 'set -o vi'.

For some reason, it's in insert mode, instead of command mode.

Also, attempting to retrieve a command twice via the '/' command
results in a beep.  Whereas in ksh, pressing '/' repeatly attempts
to find all occurences of the command, then it will finally beep
when no more occurences exist.

I'm running SLS 1.01 0.99p9 Linux.

Thanks!
