I've bisected the emacs-27 branch for this. The first bad commit is

--8<---------------cut here---------------start------------->8---
commit 047c1b19353ff58d8cd45935c7b44c911b70e312 (HEAD, refs/bisect/bad)

    * lisp/eshell/em-cmpl.el: Use completion-at-point i.s.o pcomplete
--8<---------------cut here---------------end--------------->8---

Since this is a serious regression, I'm marking this as blocking for
Emacs 27. (Sorry Eli, but you can always overrule me)
