[erlang-bugs] megaco flex warning

I agree the output should be either decimal or hex. Hex is likely nicer
for the usual looking upwhat characters are online, though decimal works
nicer for Erang handling given decimal is the default output.

If flex is in charge of that, I'm all for blaming Flex for the problem.

Regards,
Fred.
