Thanks for catching this. I believe this ultimately broke due to the fix 
in bug#66700, but as far as I can tell, the intended behavior (adding to 
Eshell's history file for 'eshell-command') had been broken for a lot 
longer. I've pushed a fix to the master branch for this part. This is 
one of those bits that's annoying to write regression tests for since it 
relies on interactive calls and using the minibuffer...

I don't think that should impact the other patches I've posted to this 
bug one way or the other though.
