Addressing mode PC with displacement broken?

I don't think these are all supposed to assemble to the same thing:

I just encountered the ~same weirdness:

VASM says this should be D6 3B 20 02

[xahon]

shouldn't it be move.l 0(pc,d0.w), d0, move.l -12(pc,d0.w), d0?
I also noticed that extra space within the parenthesis considered as a syntax error

[protonwrangler]

xahon, with the '020 Motorola changed the assembler syntax from the form d(An) to (d,An) -- putting everything including the constant offset inside the parens.
