format can produce 0+3

[Arthur]

In latest trunk, and afaik all earlier versions too, (format nil "~3,'0@D" 3) produces "0+3" - not "+03" as I'd expect.

22.3.2.2 (the description of ~D) says that "spaces are inserted on the left ..." and that if a pad character is provided it's used instead of #\space.

The output "0+3" certainly looks weird (if one is used to thinking of using #\0 as a pad character to produce leading zeroes), but the pad character just something that's "inserted on the left" if the digits and sign require fewer than mincol characters.

Uh, "the pad character IS just something ..."
