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.
