Watching some very large variable content looks like the variable is empty

On Vista this happens sooner than on XP, i.e. as soon as watching

d=rand(1,234)

for instance while

d=rand(1,233)

is still OK. The limit seems to be the 32k boundary (counting pixels used to display the string).

This is Tk bug 1449858.
