Simple TODO lister

[squeek502]

Nice!

You can (and probably should) avoid all realpath calls btw, will send a PR with that change in a bit (EDIT: PR created).

A few potential improvements if you’re interested:

• Output the line number along with the filename, e.g. main.zig:123
• For a bit of fun, add a --random option that outputs one random TODO/FIXME/etc (to allow using it for FIXME roulette)
  • (alternatively, make each entry output on one line so | shuf | head -n1 works)

In the implementation you could directly use if to unwrap the optional result of pop, to make the code simpler.

That would actually introduce a bug. The point of the if is to avoid closing the initial dir (context), so pop returning non-null isn’t the relevant bit of information.
