is there a stylistic preference for a trailing "--" on a command?

["Robert P. J. Day" <rpjday@xxxxxxxxxxxxxx>]

  just noticed these examples in "man git-bisect":

EXAMPLES
  $ git bisect start HEAD v1.2 --      # HEAD is bad, v1.2 is good
  ...
  $ git bisect start HEAD origin --    # HEAD is bad, origin is good
  ...
  $ git bisect start HEAD HEAD~10 --   # culprit is among the last 10

is there some rationale or stylistic significance to those trailing
"--" on those commands? i assume they have no effect, just curious as
to why they're there.
