`eshell/which' doesn't respect quoted commands

[Emilio Lopes]

`eshell/which' doesn't respect quoted commands, although 
`eshell-prefer-lisp-functions' is nil:

   ~ $ which ls
   eshell/ls is a compiled Lisp function in `em-ls'
   ~ $ which *ls
   eshell/ls is a compiled Lisp function in `em-ls'

The response to the second input line should be (in my system) "/bin/ls".

The following patch fix this.

        * eshell/esh-cmd.el (eshell/which): respect commands quoted with
        eshell-explicit-command-char
