Thanks.  I am wondering if we should go all the way and do

	ssize_t val;
	const char *str = getenv("CONTENT_LENGTH");

	if (!str || !*str)
		return 0;
	if (!git_parse_ssize_t(str, &val))
		die(...);
	return val;

That would match the RFC, but it seems to make t5510-fetch.sh hang,
right after

  ok 165 - --negotiation-tip understands abbreviated SHA-1

When I run with -v -i -x, it stalls at

  ++ git -C '/usr/local/google/home/jrn/src/git/t/trash directory.t5510-fetch/httpd/www/server' tag -d alpha_1 alpha_2 beta_1 beta_2
  Deleted tag 'alpha_1' (was a84e4a9)
  Deleted tag 'alpha_2' (was 7dd5cf4)
  Deleted tag 'beta_1' (was bcb5c65)
  Deleted tag 'beta_2' (was d3b6dcd)
  +++ pwd
  ++ GIT_TRACE_PACKET='/usr/local/google/home/jrn/src/git/t/trash directory.t5510-fetch/trace'
  ++ git -C client fetch --negotiation-tip=alpha_1 --negotiation-tip=beta_1 origin alpha_s beta_s

Do you know why?

Thanks,
