No, it does not look the same. 'ls' will columnize the output to fit
every file its listing--but it will vary the column widths for each
execution. Thus, calling 'ls' on all files at once looks better than
calling it seperately for each file involved. Yeah, its completely
cosmetic, but its also easier to read. xargs is also undesired because it
would still do the same as -exec, that being calling ls seperately for
each file... Compare:

The first is listing all files at once, where the latter is listing them
seperately. The data is the same, but what is easier to read?
