[PATCH] some minor fixes for Tramp

[Brian Cully]

Attached is a patch for a few functions that cleans up remote path 
names before being passed to a REPL running remotely via Tramp. I 
haven't done a thorough audit of the code to see where else things 
might need to be adjusted, this is just what I've run across 
through my own use.
