[Mono-list] RegExp Bug ...

[John Duncan]

Hans,

It's interesting to me that the two results are different but I also am 
curious as to what you're trying to accomplish. The regular expression 
should also match the "ny" in "Sunny" just the same as it should match 
the "ddy" in "paddy".

Kind of strange.... Is that are you trying to accomplish? (You are 
right, of course, that mcs is errant here.)

John
