Thanks for fixing that up.

After a bit of looking at the `eshell-do-eval' implementation, I 
realized that there's a better solution that's very simple. See the 
attached patch. It's simple enough that it might be fine for Emacs 28, 
but the existing change on the 28 branch is probably a bit safer, since 
that change was just a partial revert. I'm not aware of anything that 
could be broken by this new patch, but you never know...

This doesn't do anything more elaborate like using generator.el's 
machinery here; while (I think) that would be nice to have eventually, 
we can address that in a separate bug, since it'd be a pretty big 
change. We could probably close this bug after this new patch merges.
