What ls does depends on the version of ls. I am aware of two behaviors:
1. ls defaults to one filename per line. (the original, but now rare behavior.)
2. ls examines stdout. If it is a tty, it switches to multiple filesnames per line, otherwise it puts 1 filename per line.
Since a pipe is not a tty, "ls|cat" will always be one filename per line. Ditto with using ls in a script in the manner shown above. If you really have an ls version with a third behavior, please tell us which version of unix you are using....after verifying that it is not an alias or something like that.
