Check that buffer is correctly accessed in WHERE clause

[stefandrissen]

I activated this rule today, it seems to be checking the underlying table and not the actual buffer being used:

block-level on error undo, throw.

define buffer customer for customer.
define buffer bucustomer for customer.

find first customer no-lock no-error.
for each bucustomer
   where bucustomer.custnum > 0
   and   customer.custnum > 0
no-lock:
   // false positive on buffer usage customer.custnum > 0
end.

Reproduced. Investigating root cause.
