Patch in general and idea is OK, but I don't like
the "no_raw_bytes" naming very much.
In patch #2 you use "if (!info->no_raw_bytes) {.."
which is double-negation.

"hide_raw_bytes" is better but still double negation.

Maybe something like "show_opcodes" which defaults to "false"
when used with plugins is better?

Agreed.
