Re: double-clicking on closing paren - wrong region marked

    Enter the below text into a vanilla buffer. It consists of a rather  
    long expression (3415 characters, I believe), which is all in one  
    line (rather than nicely formatted). Add a few extra lines to the  
    expression.

That is not a precise specification.  I tried this, and it worked
fine, but I have no way of telling whether this is because it doesn't
fail for me, or because it depends on how you "add a few extra lines".

"Enter the below text into a vanilla buffer" is not precise either.

Please send a _precise_ bug report.
