[PATCH v4 0/3] handle empty spec-compliant remote repos correctly

Updates:
o Included tighten-check patch from Jonathan Nieder and Junio C Hamano
  in this patch set
o Updated commit message following Jonathan Nieder's suggestion
o Updated warning messages to mention capabilities^{}

As for warning vs die, I would prefer the "liberal" approach of continuing on when facing a recoverable error (that is, "warning"). But I agree that there are good points in favor of using fatal errors ("die") and I can switch to that if there is consensus.

Jonathan Nieder (1):
  connect: tighten check for unexpected early hang up

Jonathan Tan (2):
  tests: move test_lazy_prereq JGIT to test-lib.sh
  connect: advertized capability is not a ref
