Sorry for the delay in responding, but I was travelling. Eric, would
you mind to make up some sample code snippets and output files show-
casing the bug? I'm not saying you don't have a point, but I can not
dedicate much effort to this issue at the moment and reusing your
samples might help to save time.

"The British army is going all hi-tech. Now when you phone them up you
get a disjointed digital recording saying: "Thank you for phoning the
Ministry of Defence. If you wish to declare war on the United Kingdom,
please press one. If you are the American president and require Brit-
ish forces to join your own to give the spurious impression of inter-
national cooperation, please press two. If you wish to register a com-
plaint about the massacre of innocent civilians press three or hold
for an operator." (John O'Farrell, Guardian, Sat 20th July, 2002)
