By default, implicit acc operands are shown, e.g. "LSR A" rather than just "LSR". I like showing operands for instructions that have multiple address modes. Not everyone agrees, so now it's a setting. They're shown by default, but enabling the option will strip them on-screen, in generated assembly, and in the instruction chart. They are always omitted for ACME output, which doesn't allow them. (issue #162)
