Michael Martin 23700276a6 Introduce wide-mode override opcodes. 
This solves the --no-collapse problem by letting you force
Absolute mode on an instruction by instruction bases, which is
usually going to be what you want anyway.

README 

Ophis is a cross-assembler for the 65xx series of chips. It supports
the stock 6502 opcodes, the 65c02 extensions, and syntax for the
"undocumented opcodes" in the 6510 chip used on the Commodore
64. (Syntax for these opcodes matches those given in the VICE team's
documentation.)

Ophis is written in pure Python and should be highly portable.
