Removing redundant and dead code.
Removing redundant and dead code.

There were two problems with the code I just removed:
1. The subsequent commands overwrote the aliases in the code I removed.
2. Even if they weren't being overwritten by subsequent, the alias wouldn't work

Darwin's ls doesn't support --format and --color options. It has a different
technique that I'll investigate later.

I have to say, I like the 'ls' being formatted the way the removed code
intended. So, it's not something I'm inclinded to neglect for long.
