Fix "--pretty=format:" for parent related items.

There are two breakages in the %P/%p interpolation.  It appended
an excess SP at the end of the list, and it gave uninitialized
contents of a buffer on the stack for root commits.

This fixes it, while updating the t6006 test which expected the
wrong output.
