Log Message:
Changes 1.8.3.3:
* "git apply" parsed patches that add new files, generated by programs
  other than Git, incorrectly.  This is an old breakage in v1.7.11.
* Older cURL wanted piece of memory we call it with to be stable, but
  we updated the auth material after handing it to a call.
* "git pull" into nothing trashed "local changes" that were \ 
in the
  index.
* Many "git submodule" operations did not work on a submodule at a
  path whose name is not in ASCII.
* "cherry-pick" had a small leak in its error codepath.
* Logic used by git-send-email to suppress cc mishandled names like
  "A U. Thor" <author@example.xz>, where the human readable part
  needs to be quoted (the user input may not have the double quotes
  around the name, and comparison was done between quoted and
  unquoted strings).  It also mishandled names that need RFC2047
  quoting.
* "gitweb" forgot to clear a global variable $search_regexp upon each
  request, mistakenly carrying over the previous search to a new one
  when used as a persistent CGI.
* The wildmatch engine did not honor WM_CASEFOLD option correctly.
* "git log -c --follow $path" segfaulted upon hitting the commit that
  renamed the $path being followed.
* When a reflog notation is used for implicit "current branch",
  e.g. "git log @{u}", we did not say which branch and worse said
  "branch ''" in the error messages.
* Mac OS X does not like to write(2) more than INT_MAX number of
  bytes; work it around by chopping write(2) into smaller pieces.
* Newer MacOS X encourages the programs to compile and link with
  their CommonCrypto, not with OpenSSL.
Also contains various minor documentation updates.
