Hmm. `--list-rules` doesn't seem to work (in the docker version anyway), and I threw it at an absolutely awful Makefile (cyclic dependencies, variable spelling errors making them empty, several other clear problems) both before and after I rewrote the whole thing... ... and it's only complaining about targets over 5 lines long (really? some of the CLI tools I'm running take 20+ lines of flags spread out for readability, I'm not going to shrink that) and one or two missing .PHONY markers (it's correct about those). There's one fewer missing .PHONY after my rewrite. Given the list in the rules folder, kinda seems like it doesn't check enough to be useful. As much as I would truly love a brutal make checker.
