Hello,

after long time (~6 moths) i manually updated my pywikibot (to nightly version 2018-06-06) 

But I found very serious BUG:

pwb.py newitem -namespace:0 -unconnectedpages:5000 

ignores -namespace parameter and imports all pages.

how to set namespace now? In pagegenerators.py is this parameter now with some exceptions, but newitem.py is not between them.

And how and why was this changed? I did'nt noticed this BREAKING change in pywikibedia-bugs mails
