Thanks. I missed the original message. The patch looks good to me, 
although it compiles with the following warning:

  In eshell-electric-forward-slash:
  ../../lisp/eshell/em-elecslash.el:98:18: Warning: Unused lexical 
variable `localname'

Looking through the code, I think we can just remove that variable.

Since this is a small change, and fixes a corner case in a new feature, 
I think it would make sense to go on the release branch, though I'll 
defer to you on this, Eli. The fact that the new code (with the removal 
of 'localname') is a bit simpler helps too.
