One would have to count only warnings with unique locus (i.e. sort -u them
after grepping them from logs).
But even with 20%, if one spends the energy to analyze the 80%, where
one actually has to analyze the code, just mechanically changing a couple of
common comment kinds into more standardized one isn't going to be
significant.
