Did not change the format character, as pymavlink seems to need it, due to a bug: ArduPilot/pymavlink#965

the 'e' already has the * 100 built in, so if we added the B it would apply twice, and get the wrong answer

we should probably change the '0' to a '-' meaning no multiplier (thanks @peterbarker )

I don't think it applies twice. At least not in my testing. I vaguely remember that the MAVProxy logic is that if a format with multiplier is found, then the separate multiplier is not taken into account.

I would prefer changing the format e into i, but seeing this triggered some unwanted behaviour last time, I thought I'd double-dip and do scaling via both the format and the individual multiplier. Mostly because doing it right doesn't seem to work correctly: ArduPilot/pymavlink#965.

It's not a big deal, let's discuss live.
