"""Add message to codereview issue.
This script takes a codereview URL or a codereview issue number as its
argument and a (possibly multi-line) message on stdin. It then calls
`git cl upload` to append the message to the given codereview issue.
Usage:
echo MESSAGE | %prog -c CHECKOUT_PATH CODEREVIEW_ISSUE
or:
cd /path/to/git/checkout
%prog CODEREVIEW_ISSUE <<EOF
MESSAGE
EOF
