bug#46137: 27.1.90; Eshell TAB completion adds TAB to prompt

[Pedro]

1: emacs -Q -nw

2: M-x eshell

3: /bin/ls Mu<TAB> # completes to Music

4: observe TAB character after '$' prompt

Does not happen if I use the eshell/ls command

Tested builds of master, emacs-27, and emacs-26 branches. This behavior 
is not present in emacs-26.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I can reproduce this problem in Emacs 27.2, but not in Emacs 29, so it
looks like it's been fixed in the time since this was reported, and I'm
therefore closing this bug report.
