Subject: [PATCH] sh(1): interactive mode improvement

In the default configuration add 2 bindings which has been requested by
many during the HEADSUP discussion:
* csh like arrow history navigation
* ctrl-arrow to jump from word to words

Add an alias to make the history command exist as an alias to fc -l.
