Do not emulate shell expansions

`~` is expanded by the shell before being passed to the program.
Programs don't need to re implement this.  Compare:

    > file ~/.profile
    /home/fredefox/.profile: ASCII text
    > file "~/.profile"
    ~/.profile: cannot open `~/.profile' (No such file or directory)

You can test what something expands to with `echo`:

    > echo ~/.profile
    /home/fredefox/.profile
