You're right here. It seems to handle pushdminus for that third
form yet that form should not be affected by pushdminus.

The patch looks correct to me. However, it leaves some code that I
believe to be redundant (prepending `-' or `+' to $tmp1 only to
ignore it by using $tmp1[2,-1]) so I suggest the following patch
instead which I think makes the code a bit simpler (hopefully
without breaking it).

Thanks for the bug report
