RFR: 200: git-info should show link to review

[Erik Helin]

Hi all,

please review this patch that adds the flag `--review` to `git-info`. This
allows a user to show the link to the pull request for a given commit, for
example in the Skara repository:

$ git info --review --no-decoration 914cbefe88a059db12e9e55ac6a3168c75a005fd
https://git.openjdk.java.net/skara/pull/322

Thanks,
Erik
