Merge branch 'jk/eoo'

The command line parser learned "--end-of-options" notation; the standard convention for scripters to have hardcoded set of options first on the command line, and force the command to treat end-user input as non-options, has been to use "--" as the delimiter, but that would not work for commands that use "--" as a delimiter between revs and pathspec. * jk/eoo: gitcli: document --end-of-options parse-options: allow --end-of-options as a synonym for "--" revision: allow --end-of-options to end option parsing
