Subject: bug#27844: 26.0.50; Dired w/ eshell-ls doesn't support wildcards in file name
Date: Thu, 27 Jul 2017 12:27:05 +0900

Dired with eshell-ls doesn't handle wildcards in file names.
emacs -Q -l em-ls -eval "(customize-set-variable 'eshell-ls-use-in-dired t)"

I)
M-: (dired source-directory) RET
C-x d lisp/*.el RET

II)
;; Following works but it shows full file name, instead of the
;; more common relative file name.
C-x d lisp/simple.el RET

    Dired w/ eshell-ls: Handle shell wildcards in file name
    
    * lisp/eshell/em-ls.el (eshell-ls--insert-directory):
    Use eshell-extended-glob (Bug#27844).
    * test/lisp/dired-tests.el (dired-test-bug27844): Add test.
