To Smurf and Andrew:
  Did you notice that there's a tag named "master" in the smurf
mm-trees.git repo,
this would confuse the git and the users, please consider remove the
"master" tag, OK?

To Git developers:
  I found that different git subcommand have inconsitent processing
about ambiguous refname,

git show will take "master" tag first,
while git tag -v will take "master" branch first,

So what's your suggestion to fix this? Just simple remove ambiguous refnames?

Or we can add a feature to allow same refname in different namespaces
(tags and branches)?
Such as "-b" to refer a branch while "-t" to refer a tag name? Else
how to distinguish them?
