Specifying file/directory on the command line does nothing

[bandithedoge]

Version
b6671c1 (also happens on 0.4.3)

Describe the bug
Directory/file paths added to the command line are ignored and zlint recursively checks everything in the current directory anyway.

To Reproduce
zig-out/bin/zlint src/semantic or zig-out/bin/zlint src/semantic/Semantic.zig

Expected behavior
zlint only checks the specified path

Yeah this feature needs to be added. This is next up on my list, after I improve no-undefined a bit. PRs welcome :)
