git_recent_tag fails to return "The most recent tag." #16

git_recent_tag is documented to return "The most recent tag."

In my hands, it does not reliably do this.

The implementation seems to assume that git tag results are necessarily in order of their creation, but this is not true.

I expect the following is a better implementation:

git_recent_tag<-function () utils::head(git('tag --sort=-taggerdate')$stdout,1L)
