is the standard "[<options>]", and not "[options]" or other?

  more pedantry -- was digging through "man git-diff" and noticed the
inconsistency in how options are represented. first, in the synopsis,
you see "[options]":

  SYNOPSIS
    git diff [options] [<commit>] [--] [<path>...]
    git diff [options] --cached [<commit>] [--] [<path>...]
    git diff [options] <commit> <commit> [--] [<path>...]
    git diff [options] <blob> <blob>
    git diff [options] [--no-index] [--] <path> <path>

while just below that in DESCRIPTION, it's all "[--options]":

  git diff [--options] [--] [<path>...]
           ^^^^^^^^^^^

a further search produced this from RelNotes/2.7.0.txt:

  "A couple of commands still showed "[options]" in their usage string
   to note where options should come on their command line, but we
   spell that "[<options>]" in most places these days."

so, "git diff -h" does in fact use the allegedly encouraged syntax:

  $ git diff -h
  usage: git diff [<options>] [<commit> [<commit>]] [--] [<path>...]
  $

but should the man pages be updated similarly? i can whip up a patch for that unless someone wants to comment on this further.
