It doesn't matter, as long as three per character entered is the longest it 
ever needs to be.  The QTextEdit's max length property will never affect it 
as long as it's sufficiently large; it's only set so it can be used as 
somewhere to store the max length variable without adding another variable 
to the class :)

Oh, I'll sort that out tomorrow.

That might make sense - it's only a warning that the user can click through, 
and it would provide a no-brain default to warn against useless passwords 
without the programmer using KPasswordDialog needing to think of a strength 
for their situation.
