Character class %g is missing

%g represents all printable characters except space

That was added in Lua 5.2 so does not apply to FH V5 & V6 and only to applies to FH V7 with Lua 5.3.
Thus, adding that class will need a caveat that it cannot be used if backward compatibility is required.

Done -- do you happen to know when it was introduced -- 5.2 or 5.3?

Thanks for answering my question at the same time as I asked it, Mike

Have noted that it doesn't apply to 5.1, but suspect you're the only author who cares about backwards compatibility.
