DESCRIPTION

-This runs `git-fsck-objects --unreachable` using the heads
-specified on the command line (or `$GIT_DIR/refs/heads/\*` and
-`$GIT_DIR/refs/tags/\*` if none is specified), and prunes all
-unreachable objects from the object database. In addition, it
+This runs `git-fsck-objects --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 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 the explicitly named <head>s are *not* appended to the
