ugly unreasonable patch, help would be appreciated

Hi,

I saw this comment and read the code for curiosity:

for (; cf>=leg.begin() && (*cf)->date()==paymentDate; --cf)

my question is

is it legal to decrement an iterator when it is at .begin()?
can this ever be false: "cf>=leg.begin()"?

it reminds me the trick to do a backward for loop with a size_t.

or maybe it is just nonsense...
