Git 1.8.3.2

The second maintenance release for 1.8.3.x series is now available at the usual places. It contains the following fixes that have already been applied to the 'master' branch for 1.8.4.

• Cloning with "git clone --depth N" while fetch.fsckobjects (or transfer.fsckobjects) is set to true did not tell the cut-off points of the shallow history to the process that validates the objects and the history received, causing the validation to fail.
• "git checkout foo" DWIMs the intended "upstream" and turns it into "git checkout -t -b foo remotes/origin/foo". This codepath has been updated to correctly take existing remote definitions into account.
• "git fetch" into a shallow repository from a repository that does not know about the shallow boundary commits (e.g. a different fork from the repository the current shallow repository was cloned from) did not work correctly.
• "git subtree" (in contrib/) had one codepath with loose error checks to lose data at the remote side.
• "git log --ancestry-path A...B" did not work as expected, as it did not pay attention to the fact that the merge base between A and B was the bottom of the range being specified.
• "git diff -c -p" was not showing a deleted line from a hunk when another hunk immediately begins where the earlier one ends.
• "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22" incorrectly when your previous branch was "frotz" (it should be rewritten to "git merge frotz~22" instead).
• "git commit --allow-empty-message -m ''" should not start an editor.
• "git push --[no-]verify" was not documented.
• An entry for "file://" scheme in the enumeration of URL types Git can take in the HTML documentation was made into a clickable link by mistake.
• zsh prompt script that borrowed from bash prompt script did not work due to slight differences in array variable notation between these two shells.
• The bash prompt code (in contrib/) displayed the name of the branch being rebased when "rebase -i/-m/-p" modes are in use, but not the plain vanilla "rebase".
• "git push $there HEAD:branch" did not resolve HEAD early enough, so it was easy to flip it around while push is still going on and push out a branch that the user did not originally intended when the command was started.
• "difftool --dir-diff" did not copy back changes made by the end-user in the diff tool backend to the working tree in some cases.
