Doesn't span hosts for URL redirects.

[chfoo]

In Wget, redirects seem to be strongly followed despite not specifying --span-hosts. eg: www.schemer.com (302) → accounts.google.com (302) → www.schemer.com (200). It also ignores --exclude-domains and possible other options.

Wpull doesn't follow this semantic. It either should or not, but it should also provide an option like --no-strong-redirects or --strong-redirects depending on whether which is best.

Forgot to cross-reference in commit message: Commit 360ae9b implicitly enables --span-hosts when not --recursive.

In addition, an extra key strong_redirect should be made available in the reason dict for the scripting hooks.
