> Not sure how I got it, but I ended up with an empty .cqlsh_history file.  In that state, when starting cqlsh, you end up with:
> bone@zen:~/dev/boneill42/cassandra-> bin/cqlsh 
> Traceback (most recent call last):
>   File "bin/cqlsh", line 2588, in <module>
>     main(*read_options(sys.argv[1:], os.environ))
>   File "bin/cqlsh", line 2543, in main
>     readline.read_history_file(HISTORY)
> IOError: [Errno 22] Invalid argument
> Its a simple fix to check for a non-empty history file.  I'll attach the patch.
