[PATCH 0/4] permit -h/--help-all in more scenarios

This series depends on ua/t1517-short-help-tests with some fixes, which show up in the first patch. Merge that branch to a new topic branch, then apply this series.

This series enables --help-all outside of repository contexts, and allows -h with other arguments (without breaking existing ls-remote/grep usage).

It consists of preparatory steps (fixes for a dependency branch; refactoring to make an internal helper's arguments clearer) followed by the main commits.

D. Ben Knoble (4):
  t1517: fixup for ua/t1517-short-help-tests
  parse-options: name flags passed to usage_with_options_internal
  builtin: also setup gently for --help-all
  builtins: show help on "-h"/"--help-all" with more than 2 arguments
