[PATCH 0/6] http: push and test fixes

This series applies on top of pu, and should apply cleanly on top of Shawn's v3-smart-http branch.

Patch 1: fixes a bug in http-push.c when fetching packs. This issue is
  minor and is unlikely to be triggered by normal users (for a possible
  trigger, see the "http-push fetches packed objects" test in
  t5540-http-push).

Patch 2: here, I collect my comments to Shawn's "Move WebDAV HTTP push
  under remote-curl" on the disabling of messages to stderr when
  --helper-status is used with http-push. I hope this will make it
  easier for Shawn to squash into his series, in the event he decides
  to.

Patch 3: also in response to Shawn's "Move WebDAV HTTP push under
  remote-curl", I collect here my mini-patch to add more reports for
  transport-helper. Again, I hope this will make it easier for Shawn to
  squash into his series.

Patch 4-7: update tests, as Shawn's patches changed the behaviour of
  the http push mechanism (dumb).

Tay Ray Chuan (7):
  http-push: fix check condition on http.c::finish_http_pack_request()
  http-push: allow stderr messages to appear alongside helper_status
    ones
  http-push: add more 'error <dst> <why>' status reports
  t5540-http-push: expect success when pushing without arguments
  t5540-http-push: check existence of fetched files
  t5540-http-push: when deleting remote refs, don't need to branch -d
    -r
  t5540-http-push: remove redundant fetches
