`dir` and `vdir` are missing

From the GNU docs:

dir is equivalent to ls -C -b; that is, by default files are listed in columns, sorted vertically, and special characters are represented by backslash escape sequences.

(source)

vdir is equivalent to ls -l -b; that is, by default files are listed in long format and special characters are represented by backslash escape sequences.

(source)

Instead of making entirely separate utilities, we should probably just make these shorthands for ls much like how hashsum and test are set up.

For this approach, the GNU decoded project might be helpful: https://www.maizure.org/projects/decoded-gnu-coreutils/ls.html.

It explains that GNU uses a mode variable that is set to either ls, dir or vdir, which changes the behaviour of the program.

Do the changes made by the dir or vdir invocations need to be overwritable ? For example dir is a shortcut for ls -C -b but can you overwrite -C using something like dir -l ?

[tertsdiepraam]

I just did a quick test and I think the answer is yes. dir -l outputs the long format and vdir -C outputs the column format.

Ok thanks.

I think we are good now!
