Usage:

Commands:
    fetch   Just fetch the change as FETCH_HEAD
    help    Show this help, or for a specific command
    pull    Pull a change into current branch
    push    Push HEAD or a local branch to Gerrit for a specific branch
Any other Git commands that support refname would work as:
    git fetch URL CHANGE && git COMMAND OPTIONS FETCH_HEAD{@|^|~|:}ARG -- ARGS
See '$FUNCNAME help COMMAND' for more information on a specific command.
Example:
    $FUNCNAME checkout -b topic 1234/5
works as:
    git fetch http://DOMAIN/p/PROJECT refs/changes/34/1234/5 \\
      && git checkout -b topic FETCH_HEAD
will checkout a new branch 'topic' base on patch-set 5 of change 1234.
