Fix our printf implementation to follow spec: if a star parameter
value for a precision is negative, act as though precision weren'tspecified at all, that is the whole .* part of the format spec shouldbe ignored. Our previous coding took it as .0 which is certainlywrong. Per report from Kris Jurka and local testing.Possibly this should be back-patched, but it would be good to getsome more testing first; in any case there are no known cases wherethere's really a problem on the backend side.
