Inconsistent and unexpected cd behaviour

The cd command is inconsistent with normal shell semantics:

$ cd
$ pwd
~/Documents
$ cd ~
$ pwd
~
$ cd $HOME
$ pwd
~

All three should result in the same pwd result.

Also, and this should perhaps be a separate issue, the fact that dot files live in ~/Documents, e.g., ~/Documents/.ssh, and not in ~/ directly means that scripts and configs that I would normally share between hosts will have to have special logic for a-shell.

For example, in .ssh/config, I have to refer to IdentityFile entries as ~/Documents/.ssh/fileName, and not as ~/.ssh/fileName.
