[Configobj-develop] Is this a bug? Quoted and non-quoted words in a single line

[Jeff B. <its...@gm...>]

ConfigObj raises a parse error when it finds a line with quoted and
non-quoted words in the same line.  The original failure was
discovered when someone tried to write an email as

    email = "name" <na...@ex...>

I'm attaching a patch with a failing test.  It's against
configobj_test.py from the latest configobj.zip, since I didn't find
the test file in svn.

Cheers,
Jeff Balogh
