fix clang -Wtautological-compare with unsigned enum
Create a GREP_HEADER_FIELD_MIN so we can check that the field value is
sane and silence the clang warning.
Clang warning happens because the enum is unsigned (this is
implementation-defined, and there is no negative fields) and the check
is then tautological.
