peel_onion(): add support for <rev>^{tag}
Complete the <rev>^{<type>} family of object descriptors by having <rev>^{tag} dereference <rev> until a tag object is found (or fail if unable). At first glance this may not seem very useful, as commits, trees, and blobs cannot be peeled to a tag, and a tag would just peel to itself. However, this can be used to ensure that <rev> names a tag object: $ git rev-parse --verify v1.8.4^{tag} 04f013dc38d7512eadb915eba22efc414f18b869 $ git rev-parse --verify master^{tag} error: master^{tag}: expected tag type, but the object dereferences to tree type fatal: Needed a single revision Users can already ensure that <rev> is a tag object by checking the output of 'git cat-file -t <rev>', but: * users may expect <rev>^{tag} to exist given that <rev>^{commit}, <rev>^{tree}, and <rev>^{blob} all exist * this syntax is more convenient/natural in some circumstances Signed-off-by: Richard Hansen <> Signed-off-by: Junio C Hamano <>
