That should be possible by defining 'pcomplete/eshell-mode/CMD', but 
that runs into two issues: 1) it's annoying to manually write all of 
these, and 2) there may be other contexts in Eshell we want to 
tab-complete remote directories that aren't covered by the 
command-specific Pcomplete functions like that.

(#1 should be fixable with a new version of 'eshell-eval-using-options', 
but I haven't looked at that in much detail yet.)
