Documentation Directions

[Jon Loeliger <jdl@freescale.com>]

Couple of questions regarding documentation direction:

- Is the plan to update all docs to use $GIT_DIR instead of .git?

- Do we intend on adding explicit support for '--help' on most,
  if not all, of the git commands?  In some cases (git-branch)
  a -*) case tacitly catches --help and usage()'s it.  In other
  cases (git-pull) this can't be done as -*) passes options
  on to git-fetch.  I think that we should catch --help directly
  so that it doesn't emit git-fetch's *) catch-all usage:

    % git pull --help
    usage: git-fetch-pack [-q] [-v] [--exec=upload-pack] [host:]directory <refs>...
    Fetch failure: --help

- Do you want to head in the per-man-page-"Now What?" direction
  as suggested by Junio?

Thanks,
