[0/3] fetch: fix segfault, missing docs in --negotiate-only

Message

The recently added --negotiate-only option segfaults when not combined
with --negotiation-tip=*, this fixes that, and adds documentation for
it.

1/3 is a related fix to save us some work in a codepath checking the
"--negotiate-only" and other passed-in options in send-pack.c.

Ævar Arnfjörð Bjarmason (3):
  send-pack.c: move "no refs in common" abort earlier
  fetch: document the --negotiate-only option
  fetch: fix segfault in --negotiate-only without --negotiation-tip=*
