One of the tests in esh-var-tests.el failed on MS-Windows; I fixed it,
although I'm not sure it's a correct fix, because the Eshell manual
seems to say that a built-in implementation of a command should be
preferred by default?

One of the tests in eshell-tests.el also fails on MS-Windows, but I
have no idea how to fix it, nor even what are the details of the
test.  Are the 'echo' commands in that test supposed to be external
shell commands or internal Eshell commands?  If the former, it could
be a problem on MS-Windows.

(This is a good example of my gripes about the test suite, which I
described in bug#57150 yesterday: debugging a failure is unnecessarily
hard and tedious.  There's no information about the specific intent of
the test and its inner workings and assumptions, except the general
idea described in the doc string.)

Here's the failure I get:
