I thought about this some more and the extraneous quoting is fine in my 
opinion. Eshell already does that quite a bit in 'eshell-do-eval', so 
what's one more case?

Wait, that works?! (After trying it out locally, so it does!)

Looking at the code, I see why now: 'eshell-named-command' calls 
'eshell-prepare-command-hook', and that hook is where we handle local 
variables. However, I truly didn't expect that; I thought the local 
variable handling occurred in an earlier phase. The more you know...

Anyway, since this works even better than I'd expected, I've now merged 
my patch to the master branch as 3c680968e49. Closing this bug now.
