Desiderata

• Simple: Simple operation in terms of counting spaces and \n.
• Avoid "off by one" errors; make sure an empty file is reported as such.
  • Words as space or enter, followed by nonspace, followed by space? Make sure two spaces aren't two words?
• Keep Linux only.
• No flags. Only count words, not lines.
• Allow piping, as well as reading files.
  • Wonder how normal utilities handle this.
• Could use zig? => Not for now

Steps:

• Look into how C utilities both read from stdin and from files.
• ...
• Compare with other implementations, see how they do it, after I've read my own version
  • Compare with gnu utils,
  • Compare with musl/busybox implementations,
  • Maybe make some pull requests, if I'm doing something better?
