Hi!

This is fixed now in the latest snapshot. The disassembler will add an address
size override modifier if the operand would otherwise allow the assembler to
choose a cheaper addressing mode. So

        lda     $00     ; Zeropage mode: A5 00
        lda     $00     ; Absolute mode: AD 00 00

will now be disassembled as

        lda     $00     ; Zeropage mode
        lda     a:$00   ; Absolute mode

Since address size override modifiers are new in the development branch, this
feature of the disassembler won't go into the 2.9 branch (the assembler would
not be able to translate the code). Fortunately, most code does not need any
overrides.

As usual, any feedback about the changes is welcome!

Regards
