clumsy patch for h = history (n)

[Ben Abbott]

All,

Jordi has pushed a changesets that enable "history" to return a cell-string of 
the history.

These were in response to the feature request below.

        https://savannah.gnu.org/bugs/index.php?37947

At present to return the last N commands a string representation of N must be 
passed.  For example, 

        last_10_commands = history ("10");

And passing a numeric value gives an error.

        last_10_commands = history (10)
        error: history: expecting all arguments to be strings

Fixing this "correctly" on the c++ side is a lot of work.  A job I am not able 
to do, and one Jordi doesn't have time for.

A work around is to use a simple, but clumsy, m-file wrapper for built-in ... 
see the attached.

Does anyone have an opinion as to whether this should or should not be done?

Ben
