i can't comment on the causes, although your assesment seems quite
reasonable. i can say, however, that when i looked at the issue a
year or two (not more) ago, these cases were certainly not rare.
my measurements were quite unscientific, but it looked to be about
50% of the documents i examined (mostly pulled indiscriminatly from
the web).
