ls-remote: drop storing operation and add documentation.

The store operation was never useful because we needed to fetch
the objects needed to complete the reference.  Remove it.

The fetch command fetch multiple references shortly to
replace the lost "store" functionality in more a generic way.

+git-ls-remote-script(1)
+=======================
+v0.1, May 2005
+
+NAME
+----
+git-ls-remote-script - Look at references other repository has.
+
+
+SYNOPSIS
+--------
+'git-ls-remote' [--heads] [--tags] <repository> <refs>...
+
+DESCRIPTION
+-----------
+Displays the references other repository has.
+
+
+OPTIONS
+-------
+--heads --tags::
+       Limit to only refs/heads and refs/tags, respectively.
+       These options are _not_ mutually exclusive; when given
+       both, references stored in refs/heads and refs/tags are
+       displayed.
+
+<repository>::
+       Location of the repository.  The shorthand defined in
+       $GIT_DIR/branches/ can be used.
+
+<refs>...::
+       When unspecified, all references, after filtering done
+       with --heads and --tags, are shown.  When <refs>... are
+       specified, only references matching the given patterns
+       are displayed.
+
+EXAMPLES
+--------
+
+       $ git ls-remote --tags ./.
