Looks like the problem is that eshell-extended-glob doesn't correctly
case-fold filenames on macOS:
$ mkdir -p /tmp/foo
$ touch /tmp/foo/bar
$ emacs -Q -batch -l em-glob -eval '(print (eshell-extended-glob "/tmp/FOO/*"))'
"/tmp/FOO/*"

In my case, the realpath of the Emacs source directory is actually
~/Entwicklung/Emacs/master (note the capital E), but my filesystem is
case-insensitive (as is the default on macOS).
