disallow no-prefix `ipython foo=bar` argument style....

disallow no-prefix `ipython foo=bar` argument style. This style is in rc1, but will be removed in rc2. Since they don't match any flag pattern, rc1-style arguments will be interpreted by IPython as files to be run. So `ipython gui=foo -i` will exec gui=foo, and pass '-i' to gui=foo. Presumably this file won't exist, so there will be an error: Error in executing file in user namespace: gui=foo Assignments *must* have two leading '-', as in: ipython --foo=bar all flags (non-assignments) can be specified with one or two leading '-', as in: ipython -i --pylab -pdb --pprint script.py or ipython --i -pylab --pdb -pprint script.py but help only reports two-leading, as single-leading options will likely be removed on moving to argparse, where they will be replaced by single-letter aliases. The common remaining invalid option will be: ipython -foo=bar and a suggestion for 'did you mean --foo=bar'? will be presented in these cases.

      """Utilities to enable code objects to be pickled.

      Any process that import this module will be able to pickle code objects.  This

      functions can be built using new.function(code, globals()).  Eventually
