I'm afraid I am not at the moment.

The reason being I have never made changes in that 2500 line perl
script.  Please consider the change above as a random suggestion from
someone who don't/can't understand the script fully ...

I you happen to know perl well and be confident the change won't have
any side effect, I wouldn't mind if you go forward and make a patch
on your own, maybe with my Suggested-by.  That patch should also have
explicit Cc: tags to Jon and Mauro who are in the SOB chain of commit
ee2aa7590398.

        Thanks, Akira
