In the assembler output, add a blank line between the constants
and addresses in the long list of equates.
The earlier change that corrected the BIT instruction caused test
2009-branches-and-banks to fail, because it was relying on the idea
that BIT made the carry flag indeterminate. Changing a BCC to a
BVS restored the desired behavior.
This worked, sort of. The problem is that SourceGen will revert to
hex output in certain situations, such as a broken symbolic
reference. There happens to be one in the ZIPPY example, and it's
on a relative branch.
The goal with the segment stuff is to allow cc65 to treat the
source as relocatable code. In that context, a relative branch to
an absolute address doesn't make any sense, so the assembler reports
a range error.
We don't currently have a mechanism that guarantees no references
are broken (and no affordance for finding them), so we can't make
this mode the default yet.
Instead, we continue to use the generic config, but generate the
correct set of lines as comments.
