  a lightweight tag is just a reference. an annotated tag has a message
associated. Usually tags are meant as local help, whereas annotated tags
are the ones pushed to the repositories and that never change. That's
why many tools ignore non annotated tags by default unless you pass
--tags to them.

  That's because master is not at -rc1 exactly, but some commits
afterwards. Please read the git-describe manpage fully, it's _really_
well explained:

       The command finds the most recent tag that is reachable from a commit.
       If the tag points to the commit, then only the tag is shown. Otherwise,
       it suffixes the tag name with the number of additional commits on top
       of the tagged object and the abbreviated object name of the most recent
       commit.


Which means that your master is 81 commits ahead of the exact 2.0-860-rc1 tag,
at sha1 31c9d42
