The code that found a nearby data target for an instruction operand
was searching backward but not forward. We now take one step
forward, so that "LDA TABLE-1,Y" fills in automatically.
This altered 2008-address-changes, which had just this situation.
It didn't alter 2010-target-adjustment, but the existing tests were
insufficient and have been improved.
There's no easy way to make non-zero-bank 65816 code work, so I'm
punting and just generating a whole-file hex dump for those. This
renders tests 2007 and 2009 useless, so I'm hesitant to claim that
ACME support is fully functional.
