New Revision: 210736
sh: Do not enter consecutive duplicates into the history.
This simply sets a flag in libedit. It has a shortcoming in that it does not
apply to multi-line commands.
Note that a configuration option for this is not going to happen, but always
having this seems better than not having it. NetBSD has done the same.
