During a discussion with the cc65 developers, I became convinced that generating "MVN $01,$02" is wrong, and "MVN #$01,#$02" is correct. 64tass, cc65, and Merlin 32 all accept this syntax; only ACME does not. Operands without a leading '#' should be treated as 24-bit values, and have the bank byte extracted. This change updates the on-screen display and assembled output to include the '#'. The ACME generator uses a Quirk to suppress the hash mark. (It doesn't currently accept values larger than 8 bits, so there's no ambiguity.)
