State-Changed-Why:
I believe that we have probably done as much as is possible now
for this PR.   The sh in current runs the test case from the PR
without delays, and the more complex similar one from the ATF tests.

There is also now text in sh.1 which explains that there is no
guarantee that the results of a command substitution will become
available to the parent shell before all commands started by the
commend substitution have finished.

Is this sufficient to close this PR (given that this time at least
the basics of the fixes committed are correct) ?
