[PATCH v5 0/5] convert: add "status=delayed" to filter process protocol

Hi,

here is the 5th iteration of my "status delayed" topic. Patch 1 to 3 are minor t0021 test adjustments and haven't been changed since v3. Patch 4 is a minor "extract method" refactoring in convert. Patch 5 is the new feature.

Changes since v4:

* rebased the topic on top of master to resolve conflicts and be able to
  share code with on Ben Peart's bp/sub-process-convert-filter topic
  http://public-inbox.org/git/xmqq1srgm9kq.fsf@gitster.mtv.corp.google.com/

* removed invalid errno check
  http://public-inbox.org/git/64b1fda4-9f79-1bd8-ad6d-43196b808d61@web.de/

* minor documentation improvement

If you review this series then please read the "Delay" section in "Documentation/gitattributes.txt" first for an overview of the delay mechanism. The changes in "t/t0021/rot13-filter.pl" are easier to review if you ignore whitespace changes.

I also noticed that the diff around the "static int apply_multi_file_filter" looks really weird as my new function "int async_query_available_blobs" is right behind it with similar lines.

Thanks, Lars
