I was fixing some leaks the other day and came up with a few changes

http push/fetch, as I was).

I hope we're not too far off from a world where leaks are something that
pop up in your newly written code, and you're not slogging through
existing test scripts. But until then, I hope these might help others.

If you want to see the before/after, try:

  cd t
  ./t5550-http-fetch-dumb.sh -i

before and after this series. Before you get no leaks reported to stdout
with "-i", and way too many without it. After, you get the leaks for the
first test that generates them.

  [1/3]: test-lib: stop showing old leak logs
  [2/3]: test-lib: show leak-sanitizer logs on --immediate failure
  [3/3]: test-lib: check for leak logs after every test

Thanks, all of these look like strict improvements to me! Now I wish
that I had all of these changes earlier, as that would have made my
leak-fixing sessions way more enjoyable.
