would like grr to be able to import a CR to the working copy

[trentm]

Somewhat the equivalent of this:

function cr-checkout {
    local crnum=$1
    if [[ -z "$crnum" ]]; then
        echo "cr-checkout: error: missing CRNUM argument" >&2
        echo "usage: cr-checkout CRNUM" >&2
        return 1
    fi
    patchset=$(git ls-remote cr | grep "refs/changes/../${crnum}/" | cut -d/ -f5 | sort -n | tail -1)
    git fetch -f cr refs/changes/${crnum:(-2)}/${crnum}/${patchset}:cr-${crnum}-${patchset}
    git checkout cr-${crnum}-${patchset}
}

You'd grr FULL-CR.JOYENT-US-URL and that would setup on a working feature branch with the latest patchset... inferring the issue from the current commit message. It should also be updatable if re-run after a new patchset was pushed.
