#3 list_files accepted answer is wrong
There's a mistake in the 3rd challenge
List names of all the files in the current directory, one file per line.
the accepted answer is just
ls but that is incorrect because
ls does not print "one file per line", it prints them in columns side by side.
ls -l should be the accepted answer because it's the only true way to get them "one file per line".
So you either change the wording or change the accepted answer
here's an example of what I mean but plain
ls not showing "one per line"
