Two sequential help requests

If I type ls --help (or the other GNU commands I have tried) I get a
help listing.  However if I type the same sequence again I see the
command line erased on hitting ENTER.  If, after the first command
completes, I hit ENTER and then re-enter the command, it does provide
the help listing. I am using the last UBUNTU release (Hardy Heron).
Perhaps this behavior is what was intended since someone might argue
that it is not necessary to issue the same command twice, but this could
also be a bug.
