Allow help.htmlpath to be a URL prefix

Browse source 
Setting this to a URL prefix instead of a path to a local directory allows
git-help --web to work even when HTML docs aren't locally installed, by
pointing the browser at a copy accessible on the web. For example,

    [help]
      format = html
      htmlpath = http://git-scm.com/docs

will use the publicly available documentation on the git homepage.
