Change the last line to: test "${r}" != "$(git merge-base "${r}" "${l}")" and those false positives should go away.

The script is far from a complete solution to the OPs problem though. It only checks one, specific remote branch. It only checks against the current branch. It is the core of something that might be useful as another subcommand to 'git remote' though.
