[RFC PATCH v3 00/17] Return of smart HTTP

["Shawn O. Pearce" <spearce@spearce.org>]

This v3 series is a respin, and includes fixes to address reviewer
comments from v2.  The protocol specification is still omitted
from the series as I have not yet had a chance to merge reviewer
comments into the draft.

Major changes from v2:

  upload-pack:
  * multi_ack_2 renamed multi_ack_detailed

  helper:
  * options are now global
  * fetch is now a batch command (instead of fetch-multiple)
  * ftp:// no longer tries info/refs?service=git-upload-pack

  http-backend:
  * manual page
  * alternates files are now served as-is
  * uses proper QUERY_STRING parsing
  * GIT_COMMITTER_EMAIL set to REMOTE_USER, for receive-pack reflog
  * receive-pack defaults to *ON* if REMOTE_USER is set

This series is still lacking:

  * The HTTP protocol documentation
  * Tests for the smart http transport code (existing tests pass)

I don't want to rush reviews, but I'm fast running of time to work on
this series right now.  Next week I am offline for vacation... and
then its time for GitTogether '09.  I plan to work on tests for
this series and the HTTP spec document draft, but that's it until
after GitTogether '09.
