Is that where the whole description is a single long unwrapped line?  
(The case of no blank line after the first line - a message starting with 
a multi-line paragraph - should already be diagnosed.)

We've disabled the check on lengths of lines in commit messages:

        # We do not want to force a maximum line length in commit
        # revision logs, as they get in the way of copy-pasting
        # debugging session, error messages, logs, etc.
        max-rh-line-length = 0

But we could add a local check in our commit_checker script for just the 
length of the first line (alongside the checks for a first line that looks 
like a ChangeLog header or is just a single word).
