[PATCH] Add --temp and --stage=all options to checkout-index.

[Shawn Pearce <spearce@spearce.org>]

Sometimes it is convient for a Porcelain to be able to checkout all
unmerged files in all stages so that an external merge tool can be
executed by the Porcelain or the end-user.  Using git-unpack-file
on each stage individually incurs a rather high penalty due to the
need to fork for each file version obtained.  git-checkout-index -a
--stage=all will now do the same thing, but faster.

 This spawned out of the discussion of my prior --suffix patch
 and replaces it entirely.

 The output format is Junio's idea, which I happened to like a lot.
 I think I have faithfully implemented it here, but added a case
 where you can obtain temporary files for only a specific stage
 without needing to read the 'wider' 3-stage format.

 Unfortunately this change lead me down a path which changed the core
 checkout code also used by apply and read-tree.  So those commands
 could now checkout to temporary files if they wanted to.  :-)

 It currently passes all test cases, including the new one provided
 by this patch.

 Using `--` is probably a good policy in scripts.
 
 
+Using --temp or --stage=all
+---------------------------
+When `--temp` is used (or implied by `--stage=all`)
+`git-checkout-index` will create a temporary file for each index
+entry being checked out.  The index will not be updated with stat
+information.  These options can be useful if the caller needs all
+stages of all unmerged entries so that the unmerged files can be
+processed by an external merge tool.
+
+A listing will be written to stdout providing the association of
+temporary file names to tracked path names.  The listing format
+has two variations:
+
+    . tempname TAB path RS
++
+The first format is what gets used when `--stage` is omitted or
+is not `--stage=all`. The field tempname is the temporary file
+name holding the file content and path is the tracked path name in
+the index.  Only the requested entries are output.
+
+    . stage1temp SP stage2temp SP stage3tmp TAB path RS
++
+The second format is what gets used when `--stage=all`.  The three
+stage temporary fields (stage1temp, stage2temp, stage3temp) list the
+name of the temporary file if there is a stage entry in the index
+or `.` if there is no stage entry.  Paths which only have a stage 0
+entry will always be omitted from the output.
+
+In both formats RS (the record separator) is newline by default
+but will be the null byte if -z was passed on the command line.
+The temporary file names are always safe strings; they will never
+contain directory separators or whitespace characters.  The path
+field is always relative to the current directory and the temporary
+file names are always relative to the top level directory.
+
+If the object being copied out to a temporary file is a symbolic
+link the content of the link will be written to a normal file.  It is
+up to the end-user or the Porcelain to make use of this information.
