Git prompt using libgit2 (again)

No description provided.

Getting the Git tag using the following is not working.

• git_describe_workdir with a git_reference.
• git_describe_commit with a git_object obtained using git_reference_peel on the git_reference.
• git_reference_is_tag with a git_reference.
• git_reference_peel with a git_reference and GIT_OBJECT_TAG.
• git_tag_lookup with a git_reference and its oid obtained using git_reference_target following git_reference_resolve.

All of these functions return a failure code even when an existing tag is checked out using git checkout v0.0.0.

Hence, I shall iterate over all tags and look for one matching the current commit.

Test Matrix: Scenarios to Verify the Behaviour

• Repository Type
  • bare, regular
• HEAD Type
  • commit (detached), branch (attached), tag (detached)
• Repository State
  • bisecting, cherry-picking, merging, rebasing, reverting
• Repository Status
  • dirty, staged, untracked

The reason these did not work is probably the tags I was testing were unannotated tags, while these functions are provided for annotated tags.
