No, that is not possible. You can only send a message to the client
if you also return a non-zero return value and thereby prevent the
commit.

If you want to inform the user of something while also accepting the
commit, you have to do so through other means. For example, the
MacPorts project sends and email to the committer if any non-critical
problems were found with the commit.
