The fRequireMinimal flag is set when VERIFY_MINIMALDATA is given:
https://github.com/bitcoin/bitcoin/blob/master/src/script/interpreter.cpp#L259

and it's supposed to "check that the number is encoded with the minimum possible number of bytes."
https://github.com/bitcoin/bitcoin/blob/master/src/script/script.h#L204

For example ff80 shouldn't be allowed to be written as ff0080.
