[PATCH] Fix git-for-each-refs broken for tags

From: Petr Baudis <pasky@suse.cz>

Message-ID: <20061118025652.2970.10571.stgit@machine.or.cz>

Unfortunately, git-for-each-refs is currently unusable for peeking into tag comments, since it uses freed pointers, so it just prints out all sort of garbage.

This makes it strdup() contents and body values.
