[plug] Extreme text editing

[J Michael Gilks]

Thanks to everyone who has replied on this thread. It seems to be a problem 
with no quick solution, I am not yet brave enough to use dd without having an 
original copy, but it is interesting to get other peoples slant on what to 
do.
Maybe just leave it churning and do something else for a while.

Love
Mike
