In GNU ls, files are printed relative to their parent directory.
We don't have such thing, so stay as close as we can.
The result is quite good. If the given pathspec is a directory prefix,
it will be stripped, strictly following GNU ls behavior. If the pathspec
has wildcards, then the command part is stripped. Usually this is the
prefix part in the pathspec.
