Hi Steven,

I got a good night's sleep and a cup of coffee in me and so I'm a little 
more mellow this morning.  ;-)

Looking at the source code, its pretty ugly already.  Your change 
doesn't make it any more ugly and it could be argued that it is slightly 
less ugly (your patch removes the duplication of the "if( (...)" 
statement).  I also don't see any alternative that would make the code 
beautiful.  :-(

Anyway, I formally withdraw my objection to this patch.

Best regards,
gvb
