Fixed the formatting of some tables (mainly the one produced by ps
in ddb) which I broke by changing %8[l]x to %8p. Hacked the central
printf routine to not add an "0x" prefix for %p formats if the field
width is nonzero. The tables are still horribly misformatted on
64-bit machines.

Use %p instead of %8p to print pointers when the field width isn't
important.
