No it wasn't... until I now looked closer and found the calls to `rsh'.

Hm. Depending on what you think about us[1], you may think that we:

1) weren't sure if we should do that (and how: using `rsh ... ls' or
   zftp), because there may be systems without rsh (offering only
   ssh), because you may need something like .rhosts for this to work, 
   which is evil, because it can get pretty expensive, right[2]?
2) were just too lazy to implement that[3]

[1] I think I wrote the two initially, but I also think someone else
    had his fingers in them after that.
[2] This only really means that we should make it configurable: to use 
    either rsh or zftp or not try remote-completion and so on...
[3] Actually, I *had* thought about trying to do that, was slightly
    scared because of 2) and then forgot.
