argument groups duplicate arguments

This parser

def create_parser2():
    parser = argparse.ArgumentParser('foo')
    parser.add_argument('--foo', help='foo help')
    grp1 = parser.add_argument_group('bar options')
    grp1.add_argument('--bar', help='bar help')
    grp2 = parser.add_argument_group('bla options')
    grp2.add_argument('--bla', help='bla help')
    return parser

gives this command line help:

optional arguments:
  -h, --help  show this help message and exit
  --foo FOO   foo help

bar options:
  --bar BAR   bar help

bla options:
  --bla BLA   bla help

but renders to following sphinx output:

.. argparse::
  :module: foo
  :func: create_parser2
  :prog: foo
  :nodefaultconst:

   usage: foo [-h] [--foo FOO] [--bar BAR] [--bla BLA]

optional arguments
   --foo

   foo help

bar options
   --foo

   foo help

   --bar

   bar help

bla options
   --foo

   foo help

   --bar

   bar help

   --bla

   bla help

The error is probably here: https://github.com/ribozz/sphinx-argparse/blob/master/sphinxarg/ext.py#L70

The initialization of items should probably go into the loop iterating over the action groups.

You're correct about the cause of this. I'd also like to fix how positional arguments in argument groups are handled (they're partially duplicated at the moment).

[dpryan79]

This is now fixed in the develop branch. I'll post a new version on Monday at the latest with this.

The release with this fix will go out today. I had originally hoped to implement #46 in that, but it's going to take to a little while to really implement that correctly.

0.1.17 is now available on pypi.
