Worse yet, there's several places with empty code blocks, eg. [0] and [1]. Even without that, the formatting contains so much unnecessary whitespace, newlines, casts, etc; I'm not sure why, given the already massive source file. How do you even fit [2] on a screen?

[1]: https://github.com/xtellect/spaces/blob/422dbba85b5a7e9a209a...

There's a lot of code in the file that is questionable to say the least. There are unnecessary blocks ( { ... }; ) of code with unnecessary semicolons that don't serve any logical purpose.

My hunch tells me it may be the result of macro-expansion in C (cc -E ...), etc. So it's likely there's a larger code base with multiple files and they expanded it into a one large C file (sometimes called an amalgamation build) and called it a day.

By they, I mean the OP, a script or an AI (or all three).
