It works for me after a bit of testing, thanks. I don't see any 
regressions on the Eshell side of things, at least.

While it would be nice to have a way for Eshell to provide multiple 
forms of its arguments for completion (one for external commands that 
expect a flat list of strings, and another for Eshell commands), that 
seems like a lot more work that would probably be better spent 
elsewhere. (And a change like that would be too big for the release 
branch anyway.)
