Add "NAME" as a built-in so that NAME <REST_OF_LINE> will execute exactly as if REPLACEMENT <REST_OF_LINE> had been entered. For example, one can execute "alias ls ls -F" to always supply the -F option to "ls". Note the built-in is defined to avoid recursion here.

With no arguments, prints out a list of the current aliases. With only the "NAME" argument, prints out a definition of the alias with that name.
