PR bin/48875

Revert the changes that were made 19 May 2016 (principally eval.c 1.125)
and the bug fixes in subsequent days (eval.c 1.126 and 1.127) and also
update some newer code that was added more recently which acted in
accordance with those changes (make that code be as it would have been
if the changes now being reverted had never been made).

While the changes made did solve the problem, in a sense, they were
never correct (see the PR for some discussion) and it had always been
intended that they be reverted.   However, in practical sh code, no
issues were reported - until just recently - so nothing was done,
until now...

After this commit, the validate_fn_redirects test case of the sh ATF
test t_redir will fail.   In particular, the subtest of that test
case which is described in the source (of the test) as:

	This one is the real test for PR bin/48875

will fail.

Alternative changes, not to "fix" the problem in the PR, but to
often avoid it will be coming very soon - after which that ATF
test will succeed again.
