Holding issue for files with inconsistent formatting

[MooglyGuy]

I observed in a recent pull request that src/lib/formats/ap2_dsk.cpp has inconsistent operator spacing/formatting across the file. There are certainly more places in the codebase than just that file, so I'm creating this issue as a holding area for other files (and looping in their owners to determine preferred overall style).

As @galibert and @rb6502 are the copyright holders, it's up to them what the overall style should be for the file.

I consider that file to be RB's territory at this point

My preference on this has evolved over time, but I've ended up at a similar place to some of Vas's recent cleanup change lists: space out expressions, and use parens to make the intent clear even when the compiler will do the right thing anyway due to operator precedence.

Doing a quick skim on the swp30, I think that's pretty close to where OG is at too.
