    git-format-patch-for-debian: Generate DEP-3 Origin header field
    
    Instead of prepending 'commit ... upstream.' to the patch description,
    generate an Origin header field.
    
    The Origin URL is supposed to refer to something accesible in a web
    browser.  Assume by default that the patch is in Linus's repository
    and generate a URL accordingly, but provide a --url option which
    specifies the web URL for the VCS web view.  Try to recognise which
    viewer it is (gitweb, cgit or github) and generate the URL for each
    commit accordingly.
