How are the filenames listed by the '--files' option ordered?

[Adamska1008]

I start a new project and use tokei to track code lines. It seems that the filenames are not sorted in lexicographical order with --files flag. It confused me because all files in different directories are mixed together, here is what it looks like

$ tokei --files

I know the order of filenames is not really an important issue, but I think having order is always better than disorder. I would appreciate hearing the opinions of others, if you don't mind.
