A Unix directory may be implemented as a file with one entry per file, but that doesn't necessarily equate to one line of a text file. The precise format of the file is a low-level implementation detail and I doubt it would be the same on all variants of Unix. If I type cat . on HP-UX I just get gibberish, containing recognisable filenames plus a load of binary stuff - and no line-ends.
