emacs/test/eshell.el
Glenn Morris 81fb60b2aa Move eshell's self-tests to the test/ directory.
* lisp/eshell/esh-var.el: Don't require esh-test when compiling.
* lisp/eshell/em-banner.el, lisp/eshell/esh-cmd.el, lisp/eshell/esh-mode.el:
* lisp/eshell/esh-var.el, lisp/eshell/eshell.el: Move tests to esh-test.
* lisp/eshell/esh-test.el: Move to ../../test/eshell.el

* test/eshell.el: Move here from lisp/eshell/esh-test.el.
