pull args for http-auth (e.g. --user --password) are ignored

[mep85]

I am running
`grab-site https://www.site.com --no-offsite-links --wpull-args="--user 123 --password 123 --wait 1"

however I am still getting lots of 401: Unauthorized errors.

My intention with that command is to:
Archive all publicly accessible pages, as well as all linked pages that require http-auth and all linked files thereon. Pages that require http-auth are mostly directory indexes in some form or fashion, e.g. text links to PDFs, images, videos, etc. so I need to save those linked documents as well. I would like a 1 second pause between downloads to prevent rate limiting.

These are occasionally on different subdomains of the main site, but always on the same root domain (I think --no-offsite-links will allow links to other subdomains, just not other root domains?)
