[PATCH] Updating documentation to match Brandon Casey's proposed git-repack patch.

[Chris Frey <cdfrey@foursquare.net>]

I haven't heard any negative commentary on this patch, and I see
the repack patch is in next, so resending in case it was missed.

This patch clarifies the git-prune man page, documenting that it only
prunes unpacked objects.  git-repack is documented according to
the new git-repack -A behaviour, which does not depend on
git-pack-objects --keep-unreachable anymore.

 This runs `git-fsck --unreachable` using all the refs
 available in `$GIT_DIR/refs`, optionally with additional set of
-objects specified on the command line, and prunes all
+objects specified on the command line, and prunes all unpacked
 objects unreachable from any of these head objects from the object database.
 In addition, it
 prunes the unpacked objects that are also found in packs by
 running `git prune-packed`.
 
+Note that unreachable, packed objects will remain.  If this is
+not desired, see linkgit:git-repack[1].

+-A::
+	Same as `-a`, but any unreachable objects in a previous
+	pack become loose, unpacked objects, instead of being
+	left in the old pack.  Unreachable objects are never
+	intentionally added to a pack, even when repacking.
+	When used with '-d', this option

 -d::
 	After packing, if the newly created packs make some
 	existing packs redundant, remove the redundant packs.
