Hi,

While testing the new eshell module 'eshell-elecslash' I found a bug
when the default-directory is the root of a remote host. To reproduce
the problem type the following in a eshell buffer (replacing "method"
and "host" by appropriate values):

$ cd /method:host:/
$ cd / <--- here the "/" should be replaced by "/method:host:/" but
instead nothing happen

I've attached a patch to this email which fixes this issue.
