Have you tried to remove the offending let-binding and see what effect
it has on Eshell's behavior?
The commit logs don't give any help about the reason for these bindings,
and looking at the code I can't figure it out myself either, so unless
John remembers why they were added, we'll be forced to just "try and
pray".
