Simple csh-like Command History
-------------------------------

                 Key: FELIX-3341
                 URL: https://issues.apache.org/jira/browse/FELIX-3341
             Project: Felix
          Issue Type: Improvement
          Components: Gogo Shell
    Affects Versions: gogo.shell-0.10.0
            Reporter: Felix Meschberger
         Attachments: FELIX-3341.patch

Suggest to add a simple csh like command line history.

* A new command "history" is added to the Shell class listing the command history
* A new History class is added to manage a bounded, in-memory-only command history
* Commands can be reused from the history using commands following this simple syntax:

         command = ( '!' spec ) | ( '^' subst ) .
         spec = '!' event [ ':' [ 'a' | 'g' ] 's' regex ] .
         event = ( '!' | idx | '?' find | string )
         idx = [ '-' ] { 0..9 } .
         find = string ( '?' | EOL ) .
         subst = pat '^' repl '^' EOL .
         regex = str pat str repl str EOL .
