[PATCH/RFC v2 0/4] rev-parse: allow --flags to output rev-parse-like flags

[Jon Seymour <jon.seymour@gmail.com>]

This series allows git rev-parse --flags to output remaining flag-like arguments
even if such arguments are valid options to git rev-parse itself.

Previously:
  $> git rev-parse --flags -q -X --no-flags -- Y -Z
  -X

Now:
  $> git rev-parse --flags -q -X --no-flags -- Y -Z
  -q -X --no-flags

Also:
  $> git rev-parse --symbolic --no-flags --flags -X HEAD
  HEAD

Note: git rev-parse --flags still seems broken w.r.t. documentation because:
  $> git rev-parse --symbolic --flags HEAD
  HEAD
even though the documentation states that --flags does not output non-flag
arguments.

Jon Seymour (4):
  rev-parse: stop interpreting flags as options to rev-parse once
    --flags is specified
  rev-parse: Don't recognise --flags as an option if --no-flags has
    been specified.
  rev-parse: add tests for git rev-parse --flags.
  rev-parse: update documentation of --flags and --no-flags options
