sh history stores consecutive redundant lines for no reason. Fix: don't enter command into history if equal to last command. it is a minor irritant to scroll back thru sh history stepping past multiple consecutive and redundant lines, and there is no good reason for storing multiple consecutive/redundant lines. How-To-Repeat: enter the same command many times at a sh prompt.

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.
