Log Message:
Add new test case in to check (coming) bug fix for newly discovered
ash based shell bug
echo ${unset_var##$(echo a)}$(echo b)
should say "b" but instead says "a" ... the first "echo a" is not
evaluated because it cannot possibly match an unset variable, but is
not removed from the list of command substitutions, when the shell
needs to execute the 2nd cmdsub, "echo b" should be at the head of
the list, but isn't, "echo a" is still there...
This test should fail (for now) - should show 4 of 40 subtests failing.
It isn't marked as atf_expect_fail as the fix for this will be coming
later today (I will just wait at least 1 b5 build cycle so the failure
can be observed).
Detecting the bug, and the fix, are from FreeBSD.
