Subject: git-fetch: adjust to packed-refs.
X-Git-Tag: v1.4.4-rc1~43^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=fbc72799a82bb9a25657a6e30bfcd7b8fe3e5a45;p=git.git

git-fetch: adjust to packed-refs.

The command checked the presence of a ref by directly looking
into $GIT_DIR/refs directory.  Update it to use show-ref.
